Description
The highly integrated FAN6747 PWM controller 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 decrease the switching frequency with load condition.

FEATUREs
High-Voltage Startup
AC-Line Brownout Protection by HV Pin
Constant Output Power Limit by HV Pin (Full AC-Line Range)
Built-in 8ms Soft-Start Function
Two-Level Over-Current Protection (OCP) with 220ms Debounce
Short-Circuit Protection (SCP) with 15ms Debounce as Output Short
Peak-Current Mode Operation with Cycle-by-Cycle Current Limiting
Low Startup Current: 30µA
Low Operating Current: 1.7mA
Over-Temperature Protection (OTP) with an External Negative-Temperature-Coefficient (NTC)
Thermistor
PWM Frequency Decreasing at Green-Mode
VDDOver-Voltage Protection (OVP)
Internal Latch Circuit for OVP, OTP, SCP, and OCP

APPLICATIONs
General-purpose switch-mode power supplies and flyback power converters, including:
Power Adapters
SMPS with Peak-Current Output, such as for
Printers, Scanners, Motor Drivers
AC/DC NB Adapters
Open-Frame SMPS
