FAN6862  
Highly Integrated Green-Mode PWM Controller  
Features  
Description  
A highly integrated PWM controller, FAN6862 provides  
several features to enhance the performance of flyback  
converters. To minimize standby power consumption, a  
proprietary green-mode function provides off-time  
modulation to continuously decrease the switching  
frequency under light-load conditions. Under zero-load  
conditions, the power supply enters burst-mode, which  
completely shuts off PWM output. Output restarts just  
before the supply voltage drops below the UVLO lower  
limit. This green-mode function enables power supplies  
to meet international power conservation requirements.

VDD Over-Voltage Protection (OVP)  
Constant Output Power Limit (Full AC Input Range)  
Internal Latch Circuit for OVP, OTP  
The FAN6862 is designed for SMPS and integrates a  
frequency-hopping function that helps reduce EMI  
emission of a power supply with minimum line filters.  
The built-in synchronized slope compensation is  
proprietary sawtooth compensation for constant output  
power limit over universal AC input range. The gate  
output is clamped at 18V to protect the external  
MOSFET from over-voltage damage.

Feedback Open-Loop Protection with 56ms Delay  
Soft Start Time: 4ms  
400mA Driving Capability  
Other protection functions include VDD over-voltage  
protection and over-temperature protection. For over-  
temperature protection, an external NTC thermistor can  
be applied to sense the ambient temperature. When  
VDD OVP or OTP is activated, an internal latch circuit  
latches off the controller.
