THEORY OF OPERATION
Power Stage
If R14 was not present, the measured voltage would be too
low due to the low value of the current sense resistor and the
controller will not start because it will detect a shorted pin.
So R14 is required for proper operation and should be
greater than 250 W.
The power stage for the demo board is a non-isolated
coupled SEPIC converter. The controller has a built in
control algorithm that is specific to the flyback transfer
function and applies to flyback, buck-boost, and SEPIC
converters. Specifically:
V OUT
V IN
+
Duty
(1 * Duty)
Voltage Sense
The voltage sense pin has several functions:
1. Basis for the Reference of the PFC Control Loop
2. Line Range Detection
(eq. 1)
The control is very similar to the control of the
NCL30080−83 with the addition of a power factor
correction control loop. The controller has a built in
hardware algorithm that relates the output current to
a reference on the primary side.
I OUT +
V REF @ N PS
2 @ R SENSE
N PS +
N PRI
N SEC
The reference scaling is automatically controller inside
the controller. The shape of the voltage waveform on VS is
critical for the PFC loop control. The amplitude of VS is
important for the range detection. Generally, the voltage on
VS should be 3.5 V peak at the highest input voltage of
interest. Voltage on VS must not be greater than 4 V under
any operating condition. The voltage on VS determines
which valley the power stage will operate in. At low line and
maximum load, the power stage operates in the first valley
(standard CrM operation). At the higher line range,
the power stage moves to the second valley to lower the
switching frequency while retaining the advantage of
quasi-resonant soft switching.
(eq. 2)
(eq. 3)
Where:
NPRI = Primary Turns
NSEC = Secondary Turns
We can now find RSENSE for a given output current.
R SENSE +
V REF @ N PS
2 @ I OUT
Auxiliary Winding
The auxiliary winding has 3 functions:
1. CrM Timing
2. VCC Power
3. Output Voltage Sense
(eq. 4)
Line Feedforward
The controller is designed to precisely regulate output
current and can be compensated to address variation due to
line voltage variation. R14 sets the line feedforward and
compensates for power stage delay times by reducing the
current threshold as the line voltage increases. R14 is also
used for the shorted CS (current sense) pin detection. At start
up, the controller puts out a current to check for a shorted pin.
CrM Timing
In the off time, the voltage on the transformer/inductor
forward biases DOUT and D9. When the current in the
magnetic has reached zero, the voltage collapses to zero.
This voltage collapse triggers a comparator on the ZCD pin
to start a new switching cycle. The ZCD pin also counts rings

EVBUM2293/D
In certain cases when the output has significant ripple
current and the LED has high dynamic resistance, the peak
output voltage can be much higher than the average output
voltage. The auxiliary winding will charge the CVCC to the
peak of the output voltage which may trigger the OVP
sooner than expected so in this case the peak voltage of the
LED string is critical. The design of the auxiliary winding
turns ratio needs to factor in the absolute peak LED forward
voltage.
on the auxiliary winding for higher order valley operation.
A failure of the ZCD pin to reach a certain threshold also
indicates a shorted output condition.
VCC Power
The auxiliary winding forward biases D9 to provide
power for the controller. This arrangement is called
a “bootstrap”. Initially CVCC, is charged through R4 and
R13. When the voltage on CVCC reaches the startup
threshold, the controller starts switching and providing
power to the output circuit and the CVCC. CVCC discharges
as the controller draws current. As the output voltage rises,
the auxiliary winding starts to provide all the power to the
controller. Ideally, this happens before CVCC discharges to
the under voltage threshold where the controller stops
operating to allow CVCC to recharge once again. The size of
the output capacitor will have a large effect on the rise of the
output voltage. Since the LED driver is a current source, the
rise of output voltage is directly dependent on the size of the
output capacitor.
There are tradeoffs in the selection of COUT and CVCC.
A low output ripple will require a large COUT value. This
requires that CVCC be large enough to support VCC power
to the controller while COUT is charging up. A large value of
CVCC requires that R4 and R13 be lower in value to allow
a fast enough startup time. Smaller values of R4 and R13
have higher static power dissipation which lowers the
efficiency of the driver. In general for a smart lighting
application, startup time may not be as critical given that
intent is that the driver IC is always biased even when the
lamp is off.
SD Pin
The SD pin is a multi-function protection input.
1. Thermal Foldback Protection
2. Programmable OVP
Thermal Protection
There is an internal current source from the SD pin.
Placing an NTC from the SD pin to ground will allow the
designer to choose the level of current foldback protection
in the event of high temperature. Output current is reduced
when the voltage on the SD pin drops below 1 V.
Below 0.5 V on SD, the controller stops. Addition of
series or parallel resistors with the NTC can shape the
foldback curve and this can be modeled using the on-line
EXCEL® design tool. In the event that the pin is left open,
there is a soft voltage clamp at 1.35 V (nominal).
While the SD pin has a current source for the OTP, it can
be overcome raising the voltage on the SD pin. At about
2.5 V, the SD pin detects an OVP and shuts down the
controller. Typically, a zener to VCC is used for this. In this
way, the designer can set the OVP to a lower value that the
OVP threshold built into the VCC pin. The zener
programmable OVP is not implemented on this demo board.
Output Voltage Sense
The auxiliary winding voltage is proportional to the
output voltage by the turns ratio of the output winding and
the auxiliary winding. The controller has an overvoltage
limit on the VCC pin at 25.5 V minimum. Above that
threshold, the controller will stop operation and enter
overvoltage fault mode. This protection would normally be
triggered if the LED string had an open.

AUX Power Management
NOTE: While this is shown for the NCL30082 controller, the management scheme is the same for the NCL30086SMRTGEVB demo board.
Figure 2. AUX Power Management
Circuit Modifications
Interface Control Signals
Output Current
The output current is set by the value of RSENS as shown
above. It’s possible to adjust the output current by changing
RSENS. Since the magnetic is designed for 8 W, it is possible
to increase the current while reducing the maximum LED
forward voltage within limits. Changes of current of ±10 %
are within the existing EMI filter design and magnetic,
changes of more than 10 % may require further adjustments
to the transformer or EMI filter.
On/Off Control
The on/off control defaults to “on” if left open. Grounding
this pin to signal ground turns the output “off”. In “off”
mode, the output voltage will regulate to ~16 V. This is well
below the level that will cause the LEDs to pass current
resulting in a true off mode. “Off” mode is also the standby
mode. The standby power consumption is greatly affected
by the values of R4 and R13. You can see this in Figure 22
for universal mains and 230 V optimized mains.
The designer may choose to trade off start up time for
standby power consumption. In a “Smart Bulb” application,
the mains power is left on so the bulb can be controlled
remotely. This designer can choose to optimize standby
power by allowing the power on startup time to be longer
than 0.5 s since power on timing is now a one-time event.
In this case, R4 and R13 are optimized for low power
consumption rather than an optimized startup time.

Dim Control
The dim control input will accept either an analog or
PWM signal. The output has full range from 0% to 100%
output. A 0 volt input to the dim connection causes Q4 to
operate in linear mode which maintains the voltage on the
dim pin of the controller at its minimum level. At 0 volts on
the dim connection, the output voltage will be ~25 V which
is below the forward voltage of the LEDs.
