General description
The TEA19363T is a member of the GreenChip family of controller ICs for switched
mode power supplies. It is intended for flyback topologies to be used either standalone
or together with USB PD or smart charging controllers (like the TEA190x series) at the
secondary side. The built-in green functions provide high efficiency at all power levels.
The TEA19363T is compatible with multiple output voltage applications with a wide
output range from 5 V to 20 V in Constant Voltage (CV) mode. When used with a
secondary-side controller IC, like the TEA190x series, it supports Constant Current (CC)
mode down to 3 V output voltage.
To support computing applications that typically have an X-capacitor with a higher value
than 100 nF, the TEA19363T incorporates an active X-capacitor discharge function.
At high power levels, the flyback converter operates in Quasi-Resonant (QR) mode. At
lower power levels, the controller switches to Frequency Reduction (FR) in Discontinuous
Conduction Mode (DCM) operation. The peak current is limited to a minimum level.
Valley switching is used in all operating modes.
At very low power levels, the controller uses burst mode to regulate the output power.
A special optocoupler current reduction regulation has been integrated which reduces
the average optocoupler current in all modes to a minimum level. This reduction ensures
high efficiency at low power and excellent no-load power performance. As the switching
frequency in this mode is never less than fsw(min) and the burst repetition rate is regulated
to a low value, the audible noise is minimized. During the non-switching phase of the
burst mode, the internal IC supply current is minimized for further efficiency optimization.
The TEA19363T includes a wide set of protections that are safe restart protections. If
the output is shorted, the system stops switching and restarts. The output power is then
limited to a lower level. If the output is shorted, the system stops switching and restarts.
The output power is then limited to a lower level.
The TEA19363T is manufactured in a high-voltage Silicon-On-Insulator (SOI) process.
The SOI process combines the advantages of a low-voltage process (accuracy, highspeed protection, functions, and control). However, it also maintains the high-voltage
capabilities (high-voltage start-up, low standby power, and brownin/brownout sensing at
the input).
The TEA19363T enables low-cost, highly efficient and reliable supplies for power
requirements up to 75 W using a minimum number of external components.

Functional description
8.1 Supply management
The chip is supplied by high-voltage mains via the HV pin during start-up and protection
mode. When the system starts switching, the auxiliary windings take over the supply.
The IC has two supply pins, the VCCH and VCCL pins. The lower pin (VCCL) supplies
the IC directly. The higher supply pin (VCCH) is connected to the VCCL pin via an
internal voltage regulator. When used in an application, which supports multiple output
voltages, a pair of auxiliary transformer windings can be used to supply the IC efficiently
at all output levels. To supply the IC at higher output voltages, the winding with fewer
turns can be connected to the VCCL pin. At the lower output voltages, the winding
with more turns can supply the IC via the VCCH pin. The voltage capability of these
pins is chosen such that applications with an output voltage range from 3 V to 20 V are
supported optimally. When the voltage on the VCCL pin drops to below Vintegd(VCCL), the
regulator between the VCCH and VCCL pins turns on.
All internal reference voltages are derived from a temperature compensated onchip band gap circuit. Internal reference currents are derived from a trimmed and
temperature-compensated current reference circuit.
8.2 Start-up and UnderVoltage LockOut (UVLO)
Initially, the capacitor on the VCCL pin is charged from the high-voltage mains using the
HV pin. The voltage on the VCCH pin follows (via an internal diode) the voltage on VCCL
pin. In this way, the capacitor on the VCCH pin is charged. As long as VCC (the voltage
on pin VCCL) is below Vstartup, the IC current consumption is minimized. When VCC
reaches the Vstartup level, the control logic activates the internal circuitry. The IC waits
for the PROTECT pin to reach Vdet(PROTECT) + Vdet(hys)PROTECT and the mains voltage
to increase to above the brownin level. Meanwhile, the internal power-control signal
(which depends on the current at the CTRL pin) also increases to its maximum value.
When all these conditions are met, the system starts switching with soft start. In a typical
application, the auxiliary winding of the transformer takes over the supply.
During the start-up period, the VCC pin is continuously regulated to the Vstartup level
using the HV charge current. The pin is regulated until the output voltage is at its
regulation level, which is detected via the CTRL pin. In this way, the VCC capacitor
value can be limited. Due to the limited current capability from the HV pin mains voltage
dependent, the voltage on pin VCC can still drop slightly during the start-up period.

(see Figure 4). The auxiliary winding of the flyback transformer provides demagnetization
information.

TEA19363T
NXP Semiconductors
GreenChip SMPS primary side control IC with QR/DCM operation and X-capacitor discharge
At high output power, the converter operates in QR-mode. Each converter cycle starts
after the demagnetization of the transformer and the detection of the valley at the end of
the previous cycle. In QR-mode, switching losses are minimized because the external
MOSFET is switched on while the drain-source voltage is minimal.
To limit the frequency of operation and enable good efficiency, the QR operation
switches to DCM operation with valley skipping when the maximum frequency limit
(fsw(max)) is reached. This frequency limit reduces the MOSFET switch-on losses and
conducted ElectroMagnetic Interference (EMI).
At medium power levels, the controller enters Frequency Reduction (FR) mode. A
Voltage Controlled Oscillator (VCO) controls the frequency. The minimum frequency in
this mode is (fsw(min)). To maintain high efficiency, the primary peak current is kept at a
minimum level during FR-mode. Valley switching is also active in this mode.
At low power, the converter enters the burst mode. In burst mode, the switching
frequency is fsw(min).
8.4 Mains voltage measuring
In a typical application, the mains input voltage is measured using the HV pin.
The mains voltage is measured every 1 ms by pulling down the HV pin to ground and
measuring its current. This current then reflects the input voltage.
The system determines if the mains voltage is connected and its value exceeds the
brownin level using an analog-to-digital converter and digital control(see Figure 1).
When the mains exceeds the brownin level, the system is allowed to start switching (see
Figure 5).
If the mains voltage is continuously below the brownout level for at least 30 ms after
start-up, a brownout is detected and the system immediately stops switching. This period
is required to avoid that the system stops switching due to the zero crossings of the
mains or during a short mains interruption.

Figure 5. Mains voltage measuring
When the mains voltage is measured by pulling the HV pin to ground, the digital control
calculates if there is a positive dV/dt at the mains. A positive dV/dt implies that a mains is
connected.
When a mains is detected, the measuring of the mains input voltage is stopped for 6 ms
to improve efficiency. In burst mode, this waiting period is increased to 97 ms.
When succeeding samples cross the brownin level (Ibi(HV)) or the mains high level (IIH(HV);
see Figure 6), a positive dV/dt is measured.

If a positive dV/dt is not detected for 28 ms, the system assumes that the mains is
disconnected. In that case, the HV pin is continuously pulled to ground, discharging the
external X-capacitor.
8.5 Auxiliary winding
To supply the control IC efficiently, the VCCH and VCCL pins are connected to auxiliary
windings via a diode and a capacitor.
To detect demagnetization and input and output voltage, one of the auxiliary windings
is connected to the AUX pin via a resistive divider (see Figure 21 and Figure 22). Each
switching cycle is divided in sections. During each section, the system knows if the
voltage or current out of the AUX pin reflects the demagnetization, valley, input voltage,
or output voltage (see Figure 7).

When the external MOSFET is switched on, the voltage at the auxiliary windings reflects
the input voltage. The AUX pin is clamped to −0.7 V. The output current is a measure
of the input voltage. This current value is internally used to set the overpower limit on
Vsense(ipk). The demagnetization, valley and output voltages are measured as a voltage
on the AUX pin. In this way, the input voltage measurement and OVP can be adjusted
independently.

When the voltage on the PROTECT pin is below Vdet(PROTECT), the clock of the delay counter is changed from the driver
pulse to 1 ms internal pulse.
When the system stops switching, the VCCH and VCCL pins are not supplied via the
auxiliary winding anymore. Depending on the protection triggered, VVCCL is either
regulated to the Vstartup level via the HV pin or dropped down until the UVLO protection
triggered (see Table 4).
8.6.1 OverPower Protection (OPP)
The overpower protection function is used to realize a maximum output power which is
nearly constant over the full input mains.
For applications intended to operate fully in DCM mode, a constant overpower protection
level can be set by using the flat portion of the OPP curve (see Figure 8). On the other
hand, applications designed to operate in QR mode at maximum power require the OPP
level to be compensated for mains. They can be set to use the variable part of the OPP
curve.
The resistors connected to the AUX pin set the IAUX. They determine which part of the
OPP curve is used by the application.
The overpower compensation circuit measures the input voltage via the AUX pin. The
circuit outputs an overpower reference voltage that depends on this input voltage. If
the measured voltage at the ISENSE pin exceeds the overpower reference voltage
(Vopp(ISENSE)), the DRIVER output is pulled low (the primary stroke is cut short). The
overpower timer starts. In this way, the system limits the power to the maximum rated
value on a cycle-by-cycle base. If the overpower situation persists continuously for
200 ms, an overpower timeout is triggered. Figure 8 shows the overpower protection
curve.

Figure 8. Overpower protection curve
During system start-up, the maximum timeout period is lowered to 40 ms. When the
output voltage is within its regulation level, the maximum timeout period returns to
200 ms, limiting the output power to a minimum at a shorted output. Shortening the
overpower timer ensures that the input power of the system is limited to < 5 W at a
shorted output.
If the load requires more power than allowed by the OPP limit, the output voltage drops
because of the limited output power. As a result, the VCC voltage also drops and UVLO
can be triggered. To retain the same response in an overpower situation (whether UVLO
is triggered or not), the system enters the overpower protection mode when overpower
and UVLO are detected. The system entering the protection mode does not depend on
the value of the OP counter.
8.6.2 OverVoltage Protection (OVP; pins AUX and VCCL)
An accurate output OVP is implemented by measuring the voltage at the AUX pin during
the secondary stroke. As the auxiliary winding voltage is a well-defined replica of the
output voltage, the external resistor divider ratio RAUX2 / (RAUX1 + RAUX2) can adjust the
OVP level.
An accurate OVP circuit is also connected to the VCCL pin. It measures if the VCCL pin
voltage exceeds the level Vovp(VCCL) at the end of primary stroke.
An internal counter of four gate pulses prevents false OVP detection which can occur
during ESD or lightning events.
8.6.3 Protection input (PROTECT pin)
The PROTECT pin is a general-purpose input pin. It can be used to trigger one of the
protection types shown in Table 4. When the voltage on the PROTECT pin is pulled
below Vdet(PROTECT) (0.5 V), the converter is stopped.
The PROTECT pin can be used to create an OTP function. To create the OTP function,
a Negative Temperature Coefficient (NTC) resistor must be connected to this pin. When

the voltage on the PROTECT pin drops to below 0.5 V, overtemperature is detected.
The PROTECT current (maximum 74 μA) flowing through the external NTC resistor
creates the voltage. The PROTECT voltage is clamped to maximum 1.45 V. At room
temperature, the resistance value of the NTC resistor is much higher than at high
temperatures. Because of the clamp, the current out of the PROTECT pin is 1.45 V
divided by the resistance, which is much lower than 74 μA.
A filter capacitor can be connected to the PROTECT pin.
To avoid false triggering, an internal filter of 2 ms to 4 ms is applied.
8.6.4 OverTemperature Protection (OTP)
If the junction temperature exceeds the thermal temperature shutdown limit, an
integrated OTP feature ensures that the IC stops switching. OTP is a safe restart
protection.
A built-in hysteresis ensures that the internal temperature must drop 10 °C degrees
before the IC restarts.
8.6.5 Maximum on-time
The controller limits the on-time of the external MOSFET to 55 μs. When the on-time is
longer, the IC stops switching and enters safe restart mode.
8.6.6 Safe restart
If a protection is triggered and the system enters the safe restart mode (see Table 4),
the system restarts after a delay time (td(restart)). An internal current source (ICC(dch))
discharges the voltage on pin VCCL. The discharge allows the conditions at a restart
to be similar to a normal start-up. Because the system is not switching, the VCCL and
VCCH pins are supplied from the mains via the HV pin.
After the restart delay time (td(restart)), the control IC measures the mains voltage. If the
mains voltage exceeds the brownin level, the control IC activates the PROTECT pin
current source and the internal voltage sources connected to the CTRL pin. When the
voltages on these pins reach a minimum level, the soft start capacitor on the ISENSE pin
is charged and the system starts switching again.
The VCC is continuously regulated to the Vstartup level until the output voltage is within the
regulation level again.

8.7 Optobias regulation (CTRL pin)
In a typical application, the output voltage (or current) is sensed on the secondary side
(by a TL431 or a controller such as TEA190x). The feedback signal is passed to the
primary side via an optocoupler. The optocoupler sends the current information to the
CTRL pin of the TEA19363T. (see Figure 21 and Figure 22).
The TEA19363T applies a relatively fixed voltage at the CTRL pin (the input impedance
of the CTRL pin is Rint(CTRL)). It senses the current through the optocoupler. The
TEA19363T compares the current with an internal regulation level IIO(reg)CTRL (80 μA).
The difference is integrated with a slow time constant (in ms). It is added to the control
signal that sets the output power. If the optocurrent (at CTRL pin) exceeds the regulation
level (IIO(reg)CTRL)), the control signal reduces in this way, which leads to an output power
decrease and vice versa. The optocurrent (at the CTRL pin) slowly regulates toward the
regulation level (IIO(reg)CTRL). The result is a constant optocurrent during stable operation
at all output power levels.

Figure 9. Optobias regulation
Figure 9 shows the slow optocurrent regulation loop.
In addition to the slow optocurrent regulation loop described above, the CTRL current
directly contributes to the internal power control by creating a voltage drop across a 6 kΩ
resistor (See Figure 9). It determines the transient behavior of the power regulation loop,
which remains similar to ICs, like the TEA1836. The control loop responds to load or
line variations through this direct optocurrent contribution, whereas the slow offset loop
simply sets the steady state operation point.
The advantages of this type of regulation are:
• The optocoupler collector parasitics do not influence the loop. So, more freedom in
tuning the loop characteristics is ensured.
• Unlike the traditional situation where the optocoupler current becomes much higher at
lower output power, it retains the same low value in steady state at all powers.
Since the optocurrent is only 80 μA even at low powers, a load step to a very high
load can result in a maximum decrease of the optocurrent by this amount only. It limits
the possible power increase. To counter this possibility, the offset loop enters a fast
regulation mode when a significant optocurrent decrease is detected (to about 20 μA

NXP Semiconductors
GreenChip SMPS primary side control IC with QR/DCM operation and X-capacitor discharge
under the regulation level). The fast regulation mode ensures a quick output power
increase.
8.8 Burst mode operation
When the output power drops to below the minimum level the system can supply while
operating at the minimum power setting (i.e. the switching frequency is at its minimum),
it can no longer reduce the optocurrent level to the regulation level IIO(reg)CTRL (= 80 μA).
In this situation, the optocurrent increases to exceed the level of the burst threshold
(Ith(burst)CTRL) and the burst mode is entered. Switching is paused and a burst-off period
commences. Consequently, the optocurrent decreases. When it drops to below the
Ith(burst)CTRL, a new burst of switching cycles is started (see Figure 10 and Figure 11).
Figure 10 shows that all the operating frequencies are outside the audible area. The
minimum switching frequency is fsw(min) and the burst mode repetition target period is
tburst.
The requested output power determines the number of pulses at each burst period. At
higher output power, the number of switching pulses increases. At low load, it decreases.
This burst mode regulation allows low-load operation without compromising on spectral
purity, while keeping the output ripple limited. In addition, the optocoupler current is
maintained at a very low level during low-load and standby operation. The result is a very
low standby power consumption.
To ensure good efficiency at very low load, the minimum number of switching cycles
is set to 1. When the minimum number of pulses is reached, the burst repetition period
cannot be reduced further. As the power decreases, the repetition rate of the single-pulse
bursts decreases as well to a very low value. To improve further, the no-load input power
and efficiency at low load, the current consumption of the IC is lowered to 240 μA during
the non-switching period in the burst mode.

Figure 10. Burst mode operation
To achieve a good transient response at an increased output load, the system starts
switching immediately when ICTRL drops to below Istart(burst). It keeps switching until the
optocurrent exceeds the level of Istart(burst)CTRL (100 μA). However, to achieve a good
transient response at a decreased output load, the system stops switching immediately
when the optocurrent exceeds the level of Istop(burst)CTRL (200 μA) at a decreased output
load. In both situations, the calculated number of switching pulses by the internal digital
circuit is overruled for the present burst cycle.

Figure 11. Transient response in burst mode
Even though the burst-mode regulates toward a target repetition frequency, the actual
repetition rate is lower than the target because of the discrete number of switching
cycles. Increasing or decreasing the number of pulses results in a step change in the
burst repetition frequency.
Before reducing the number of pulses in the next burst, it is ensured that the resulting
repetition rate does not exceed the target frequency. Hence, at any moment in burstmode operation, the actual burst repetition rate is within a band under the target
frequency. If the number of burst pulses decreases, the effect of adding a pulse
increases and the band becomes wider (see Figure 12).

Figure 12. Upper and lower limits of burst frequency
When the burst on time is 1.5 times longer than the target period (tburst), the system
switches to normal mode again.
8.9 Soft start-up (ISENSE pin)
To prevent audible noise during start-up or a restart condition, an integrated soft start
feature is implemented. When the converter starts switching, the primary peak current
slowly increases to the regulated level with 15 steps.
The soft start time constant is 3.7 ms, set by an internal time.
