FAN6754  
Highly Integrated Green- Mode PWM Controller  
Brownout and VLimit Adjustment by HV Pin  
Features  
Description  
The highly integrated FAN6754 PWM controller  
provides several features to enhance the performance  
of flyback converters. To minimize standby power

High-Voltage Startup  
AC Input Brownout Protection with Hysteresis  
Monitor HV to Adjust VLimit  
consumption,  
a
proprietary green-mode function  
provides off-time modulation to continuously decrease  
the switching frequency under light-load conditions.  
Low Operating Current: 1.7mA  
Linearly Decreasing PWM Frequency to 22KHz  
Frequency Hopping to Reduce EMI Emission  
Fixed PWM Frequency: 65KHz  
Under zero-load and very light-load conditions,  
FAN6754 saves PWM pulses by entering deep burst  
mode. This burst mode function enables the power  
supply to meet international power conservation  
requirements.  
Peak-Current-Mode Control  
FAN6754 integrates  
a frequency-hopping function  
Cycle-by-Cycle Current Limiting  
internally to reduce EMI emission of a power supply  
with minimum line filters. Built-in synchronized slope  
compensation is accomplished by proprietary HV  
monitor to adjust VLimit for constant output power limit  
over universal AC input range. Also, the gate output is  
clamped at 13V to protect the external MOSFET from  
over-voltage damage.  
Leading-Edge Blanking (LEB)  
Internal Open-Loop Protection  
GATE Output Maximum Voltage Clamp: 13V  
VDD Under-Voltage Lockout (UVLO)  
VDD Over-Voltage Protection (OVP)  
Programmable Over-Temperature Protection (OTP)  
Latch Circuit (OVP, OTP)  
Other protection functions include AC input brownout  
protection with hysteresis and VDD over-voltage  
protection. For over-temperature protection, an external  
NTC thermistor can be applied to sense the external  
switcher’ s temperature. When VDD OVP are activated,  
an internal latch circuit is used to latch-off the controller.  
The latch mode is reset when the VDD supply is  
removed.  
Open-Loop Protection (OLP); Restart for MR, Latch  
for ML
