General Description
BD7679G is a PWM controller type DC/DC converter IC for AC/DC that provides an optimum system for all products that requires an electrical outlet. This product supports both isolated and non-isolated devices. IC enables simple design of low-power electrical converters. With switching MOSFET and current detection resistor as external devices, it enables more freedom in design.

FEATUREs
■ PWM frequency of 65kHz
■ PWM current mode method
■ Low circuit current when UVLO is ON
   (12μA at VCC=12V)
■ Low circuit current without load
   (Burst operation when load is light)
■ Built-in SW frequency hopping function
■ 250ns leading-edge blanking
■ VCC UVLO / OVP (Auto restart)
■ Per-cycle over current protection circuit
■ Soft start
■ Output overload protection(Auto-restart protection)
■ External stop function for COMP pin (Auto restart)

APPLICATIONs
   AC adapters and household appliances (vacuum cleaners,
   humidifiers, air cleaners, air conditioners, refrigerators, IH
   cooking heaters, rice cookers, etc.)
