FAN6755  
Highly Integrated Green-Mode PWM Controller  
Features  
Description  
This highly integrated PWM controller provides several  
features to enhance the performance of flyback  
converters.  
ƒ
ƒ
ƒ
Internal High-Voltage Startup  
Low Operating Current (Maximum: 2mA)  
Adaptive Decreasing of PWM Frequency to 23KHz  
at Light-Load condition to Improve Light-Load  
Efficiency  
To minimize standby power consumption, a proprietary  
adaptive green-mode function reduces switching  
frequency at light-load condition. To avoid acoustic-  
noise problems, the minimum PWM frequency is set  
above 23kHz. This green-mode function enables the  
power supply to meet international power conservation  
requirements, such as Energy Star®. With the internal  
high-voltage startup circuitry, the power loss caused by  
bleeding resistors is also eliminated. To further reduce  
power consumption, FAN6755 uses the BiCMOS  
process, which allows an operating current of only 2mA.  
The standby power consumption can be under 100mW  
for most of LCD monitor power supply designs.

Frequency Hopping to Reduce EMI Emission  
Fixed PWM Frequency: 65KHz  
Internal Leading-Edge Blanking  
Built-in Synchronized Slope Compensation  
Auto-Restart Protection : Feedback Open-Loop  
Protection (OLP), VDD Over-Voltage Protection  
(OVP), Over-Temperature Protection (OTP), and  
Line Over-Voltage Protection  
FAN6755 integrates a frequency-hopping function that  
reduces EMI emission of a power supply with minimum  
line filters. Its built-in synchronized slope compensation

Soft Gate Drive with Clamped Output Voltage: 18V  
VDD Under-Voltage Lockout (UVLO)  
achieves  
a stable peak-current-mode control and  
Programmable Constant Power Limit (Full AC  
Input Range)  
improves noise immunity. The proprietary, external line  
compensation ensures constant output power limit over

Internal OTP Sensor with Hysteresis  
Build-in 5ms Soft-Start Function  
a wide AC input voltage range from 90VAC to 264VAC  
.
FAN6755 provides many protection functions. The  
internal feedback open-loop protection circuit protects  
the power supply from open feedback loop condition or  
output short condition. It also has line under-voltage  
protection (brownout protection) and over-voltage  
protection using an input voltage sensing pin (VIN).
