FAN6754WA  
Highly Integrated Green-Mode PWM Controller  
Brownout and VLimit Adjustment by HV Pin  
Features  
Description  
The highly integrated FAN6754WA 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: 1.5 mA  
Linearly Decreasing PWM Frequency to 22 kHz  
Frequency Hopping to Reduce EMI Emission  
Fixed PWM Frequency: 65 kHz  
Under zero-load and very light-load conditions,  
FAN6754WA saves PWM pulses by entering "deep"  
Burst Mode. Burst Mode enables the power supply to  
meet international power conservation requirements.  
Peak-Current-Mode Control  
FAN6754WA also integrates  
a
frequency-hopping  
function that helps reduce EMI emission of a power  
supply with minimum line filters. The built-in  
synchronized slope compensation helps achieve stable  
peak-current control. To keep constant output power  
limit over universal AC input range, the current limit is  
adjusted according to AC line voltage detected by the  
HV pin. The gate output is clamped at 13 V to protect  
the external MOSFET from over-voltage damage.  
Cycle-by-Cycle Current Limiting  
Leading-Edge Blanking (LEB)  
Internal Open-Loop Protection  
GATE Output Maximum Voltage Clamp: 13 V  
VDD Under-Voltage Lockout (UVLO)  
VDD Over-Voltage Protection (OVP)  
Programmable Over-Temperature Protection (OTP)  
Internal Latch Circuit (OVP, OTP)  
Other protection functions include AC input brownout  
protection with hysteresis, sense pin short-circuit  
protection, 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 or OTP are activated, an internal latch  
circuit is used to latch-off the controller. The Latch Mode  
is reset when the VDD supply is removed.

SENSE Short-Circuit Protection (SSCP)  
Built-in 8 ms Soft-Start Function  
FAN6754WA is available in an 8-pin SOP package.
