FAN6753  
Highly Integrated Green-Mode PWM Controller  
Features  
Description  
The highly integrated FAN6753 PWM controller  
provides several features to enhance the performance  
of flyback converters.  
ƒ
ƒ
ƒ
ƒ
High-Voltage Startup  
Low Operating Current: 2.7mA  
Adaptive Decreasing PWM Frequency to 22KHz  
To minimize standby power consumption, a proprietary  
adaptive green-mode function provides frequency  
modulation at light-load conditions. To avoid acoustic-  
noise problems, the minimum PWM frequency is set  
above 22KHz. This green-mode function enables the  
power supply to meet international power conservation  
requirements. With the internal high-voltage startup  
circuitry, the power loss due to bleeding resistors is also  
eliminated. To further reduce power consumption,  
FAN6753 is manufactured using the BiCMOS process,  
which allows an operating current of only 2.7mA.  
Built-in Full-Range Frequency Hopping to Reduce  
EMI Emission

Peak-Current-Mode Control  
Cycle-by-Cycle Current Limiting  
Leading-Edge Blanking (LEB)  
Synchronized Slope Compensation  
Internal Auto-Recovery Open-Loop Protection  
GATE Output Maximum Voltage Clamp: 18V  
VDD Under-Voltage Lockout (UVLO)  
FAN6753 integrates a full-range frequency-hopping  
function internally that helps reduce EMI emission of a  
power supply with minimum line filters. Its built-in  
synchronized slope compensation achieves stable  
peak-current-mode control. The proprietary internal line  
compensation ensures constant output power limit over  
VDD Over-Voltage Protection (OVP),  
Auto Recovery / Latch for Option  
a wide AC input voltage range, from 90VAC to 264VAC  
.
ƒ
Internal Auto-Recovery Sense Short-Circuit  
Protection for Option  
FAN6753 provides many protection functions. In  
addition to cycle-by-cycle current limiting, the internal  
open-loop protection circuit ensures safety should an  
open-loop or output short-circuit failure occur. PWM  
output is disabled until VDD drops below the UVLO lower  
limit, when the controller starts up again. As long as VDD  
exceeds ~26V, the internal OVP circuit is triggered.
