PSR LED Driver IC for LED Lighting
Description
CY39C604 is a Primary Side Regulation (PSR) LED driver IC for LED lighting. Using the information of the primary peak current and
the transformer-energy-zero time, it is able to deliver a well regulated current to the secondary side without using an opto-coupler in
an isolated flyback topology. Operating in critical conduction mode, a smaller transformer is required. In addition, CY39C604 has a
built-in dimmable circuit and can constitute the lighting system for PWM dimming.
It is most suitable for the general lighting applications, for example replacement of commercial and residential incandescent lamps.

8. Function Explanations
8.1
LED Current Control by PSR (Primary Side Regulation)
CY39C604 regulates the average LED current (ILED) by feeding back the information based on Primary Winding peak current
(IP_PEAK) and Secondary Winding energy discharge time (TDIS) and switching period (TSW). Figure 5 shows the operating waveform in
steady state. IP is Primary Winding current and IS is Secondary Winding current. ILED as an average current of the Secondary
Winding is described by the following equation.
ILED =
TDIS
1
× IS_PEAK ×
2
TSW
Using IP_PEAK and the transformer Secondary to Primary turns ratio (NP/NS), Secondary Winding peak current (IS_PEAK) is described
by the following equation.
IS_PEAK =
NP
× IP_PEAK
NS
Therefore,
ILED=
TDIS

×IP_PEAK×
2 NS
TSW
CY39C604 detects TDIS by monitoring the TZE pin and IP_PEAK by monitoring the CS pin and then controls ILED. An internal Err Amp
sinks gm current proportional to IP_PEAK from the COMP pin during TDIS period. In steady state, since the average of the gm current is
equal to internal reference current (ISO), the voltage on the COMP pin (VCOMP) is nearly constant.
IP_PEAK × RCS × gm × TDIS = ISO × TSW
In above equation, gm is transconductance of the Err Amp and RCS is a sense resistance.
Eventually, ILED can be calculated by the following equation.

8.2
PFC (Power Factor Correction) Function
Switching on time (TON) is generated by comparing VCOMP with an internal sawtooth waveform (refer to Figure 2). Since VCOMP is
slow varying with connecting an external capacitor (CCOMP) from the COMP pin to the GND pin, TON is nearly constant within an AC
line cycle. In this state, IP_PEAK is nearly proportional to the AC Line voltage (VBULK). It can bring the phase differences between the
input voltage and the input current close to zero, so that high Power Factor can be achieved.
8.3
Dimming Function
CY39C604 has the built-in dimmable circuit to control ILED by changing a reference of Err Amp based on the input voltage level on
the DIM pin (VDIM), and realizes dimming. Figure 6 shows ILED dimming ratio based on VDIM.
Figure 7 shows the input circuit to the DIM pin for PWM dimming. PWM signal is divided and filtered into an analog voltage with RC
network. It is possible to configurate PWM dimmable system by inputting the voltage to the DIM pin.

Power-On Sequence
When the AC line voltage is supplied, VBULK is powered from the AC line through a diode bridge, and the VDD pin is charged from
VBULK through an external source-follower BiasMOS.(Figure 8 red path)
When the VDD pin is charged up and the voltage on the VDD pin (VVDD) rises above the UVLO threshold voltage, an internal Bias
circuit starts operating, and CY39C604 starts the dimming control. After the UVLO is released, this device enables switching and is
operating in a forced switching mode (TON = 1.5 µs, TOFF = 78 µs to 320 µs). When the voltage on the TZE pin reaches the Zero
energy threshold voltage (VTZETH = 0.7V), CY39C604 enters normal operation mode. After the switching begins, the VDD pin is also
charged from Auxiliary Winding through an external diode (DBIAS).(Figure 8 blue path)
Around zero cross points of the AC line voltage VVDD is not supplied from VBULK or Auxiliary Winding. It is necessary to set an
appropriate capacitor of the VDD pin in order to keep VVDD above the UVLO threshold voltage in this period. An external diode (D1)
between BiasMOS and the VDD pin is used to prevent discharge from the VDD pin to VBULK at the zero cross points.

Power-Off Sequence
After the AC line voltage is removed, VBULK is discharged by switching operation. Since any Secondary Winding current does not
flow, ILED is supplied only from output capacitors and decreases gradually. VVDD also decreases because there is no current supply
from both Auxiliary Winding and VBULK. When VVDD falls below the UVLO threshold voltage, CY39C604 shuts down.

IP_PEAK Detection Function
CY39C604 detects Primary Winding peak current (IP_PEAK) of Transformer. ILED is set by connecting a sense resistance (Rcs)
between the CS pin and the GND pin. Maximum IP_PEAK (IP_PEAKMAX) limited by Over Current Protection (OCP) can also be set with
the resistance.
Using the Secondary to Primary turns ratio (NP/NS) and ILED, RCS is set as the following equation (refer to 8.1)
RCS=
NP 0.14

NS ILED
In addition, using the OCP threshold voltage (VOCPTH) and RCS, IP_PEAKMAX is calculated with the following equation.
IP_PEAKMAX =

Zero Voltage Switching Function
CY39C604 has built-in zero voltage switching function to minimize switching loss of the external switching MOSFET. This device
detects a zero crossing point through a resistor divider connected from the TZE pin to Auxiliary Winding. A zero energy detection
circuit detects a negative crossing point of the voltage on the TZE pin to Zero energy threshold voltage (VTZETL). On-timing of
switching MOSFET is decided with waiting an adjustment time (tADJ) after the negative crossing occurs.
tADJ is set by connecting an external resistance (RADJ) between the ADJ pin and the GND pin. Using Primary Winding inductance
(LP) and the parasitic drain capacitor of switching MOSFET (CD), tADJ is calculated with the following equation.
tADJ =
π LP × CD
2
Using tADJ, RADJ is set as the following equation.
RADJ [kΩ] = 0.0927 × tADJ [ns]

Protection Functions
Under Voltage Lockout Protection (UVLO)
The under voltage lockout protection (UVLO) prevents IC from a malfunction in the transient state during VVDD startup and a
malfunction caused by a momentary drop of VVDD, and protects the system from destruction/deterioration. An UVLO comparator
detects the voltage decrease below the UVLO threshold voltage on the VDD pin, and then the DRV pin is turned to “L” and the
switching stops. CY39C604 automatically returns to normal operation mode when VVDD increases above the UVLO threshold
voltage.
Over Voltage Protection (OVP)
The over voltage protection (OVP) protects Secondary side components from an excessive voltage stress. If the LED is
disconnected, the output voltage of Secondary Winding rises up. The output overvoltage can be detected by monitoring the TZE pin.
During Secondary Winding energy discharge time, VTZE is proportional to VAUX and the voltage of Secondary Winding (refer to 8.1).
When VTZE rises higher than the OVP threshold voltage for 3 continues switching cycles, the DRV pin is turned to “L”, and the
switching stops (latch off). When VVDD drops below the UVLO threshold voltage, the latch is removed.
Over Current Protection (OCP)
The over current protection (OCP) prevents inductor or transformer from saturation. The drain current of the external switching
MOSFET is limited by OCP. When the voltage on the CS pin reaches the OCP threshold voltage, the DRV pin is turned to “L” and
the switching cycle ends. After zero crossing is detected on the TZE pin again, the DRV pin is turned to “H” and the next switching
cycle begins.
Short Circuit Protection (SCP)
The short circuit protection (SCP) protects the transformer and the Secondary side diode from an excessive current stress. When
the short circuit between LED terminals occurs, the output voltage decreases. If the voltage on the TZE pin falls below SCP
threshold voltage, VCOMP is discharged and fixed at 1.5V and then the switching enters a low frequency mode.(TON = 1.5 µs /TOFF =
78 µs to 320 µs)
Over Temperature Protection (OTP)
The over temperature protection (OTP) protects IC from thermal destruction. When the junction temperature reaches +150°C, the
DRV pin is turned to “L”, and the switching stops. It automatically returns to normal operation mode if the junction temperature falls
back below +125°C.

11. Usage Precautions
Do not configure the IC over the maximum ratings.
If the IC is used over the maximum ratings, the LSI may be permanently damaged.
It is preferable for the device to normally operate within the recommended usage conditions. Usage outside of these conditions can
have an adverse effect on the reliability of the LSI.
Use the device within the recommended operating conditions.
The recommended values guarantee the normal LSI operation under the recommended operating conditions.
The electrical ratings are guaranteed when the device is used within the recommended operating conditions and under the
conditions stated for each item.
Printed circuit board ground lines should be set up with consideration for common impedance.
Take appropriate measures against static electricity.
Containers for semiconductor materials should have anti-static protection or be made of conductive material.
After mounting, printed circuit boards should be stored and shipped in conductive bags or containers.
Work platforms, tools, and instruments should be properly grounded.
Working personnel should be grounded with resistance of 250 kΩ to 1 MΩ in serial between body and ground.
Do not apply negative voltages.
The use of negative voltages below - 0.3 V may make the parasitic transistor activated to the LSI, and can cause malfunctions.
12. RoHS Compliance Information
This product has observed the standard of lead, cadmium, mercury, Hexavalent chromium, polybrominated biphenyls (PBB), and
polybrominated diphenyl ethers (PBDE).
