FAN6862W  
Highly Integrated Green-Mode PWM Controller  
Features  
Description  
.
.
.
.
Low Standby Power: Under 0.1 W  
A
highly integrated PWM controller, FAN6862W  
provides several features to enhance the performance  
of flyback converters. To minimize standby power  
consumption, a proprietary Green Mode 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. Green Mode enables power supplies to meet  
international power conservation requirements.  
Low Startup Current: 8 µA  
Low Operating Current in Green Mode: 600 µA  
Peak-Current Mode Operation with Cycle-by-Cycle  
Current Limiting

Burst Mode at Light Loads

VDD Over-Voltage Protection (OVP)  
Constant Output Power Limit (Full AC Input Range)  
Internal Latch Circuit (FAN6862WL) for OVP, OTP  
The FAN6862W is designed for SMPS and integrates a  
frequency-hopping function that helps to reduce EMI  
emission of a power supply with minimum line filters. To  
compensate the power limit variation over universal  
input range, a bias current limit (VLIMIT) adaptively keeps  
the power limit substantially constant. The gate output is  
clamped at 13.5 V to protect the external MOSFET from  
over-voltage damage.

Hopping

Feedback Open-Loop Protection: 60 ms Delay  
GATE Output Maximum Voltage Clamp: 13.5V  
Soft-Start Time: 5 ms  
Other protection functions include VDD Over-Voltage  
Protection (OVP), and Over-Temperature Protection  
(OTP). For OTP, 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. Protection types are shown in Table 1.
