Product Description

The HFC0100 is a peak current mode controller with Green Mode Operation. Its high efficiency feature over the entire line and load range meets the stringent world-wide energy efficiency requirements. The HFC0100 integrated with a high current source, its valley detector ensures minimum Drain-Source voltage switching (Quasi-Resonant operation). When the output power falls below a given level, the controller enters the burst mode. The HFC0100 features variable protections like Thermal Shutdown (TSD), Vcc Under voltage Lockout (UVLO), Over Load Protection (OLP), Over Voltage Protection (OVP). The HFC0100 is available in the 8-pin SOIC8 package.
