HFC0100 QUASI RESONANT CONTROLLER The Future of Analog IC Technology DESCRIPTION FEATURES Universal Main Input Voltage (85~265VAC) The HFC0100 is a peak current mode controller Quasi-Resonant Operation with Green Mode Operation. Its high efficiency Valley Switching for high efficiency and EMI feature over the entire line and load range meets the stringent world-wide energy Active Burst Mode for low standby power efficiency requirements. consumption Internal High Voltage Current Source The HFC0100 integrated with a high voltage High level of integration, allows a very low current source, its valley detector ensures number external component count minimum Drain-Source voltage switching Maximum Frequency Limited (Quasi-Resonant operation). When the output Internal Soft Start power falls below a given level, the controller Internal 250nS Leading Edge Blanking enters the burst mode. Thermal shutdown (auto restart with The HFC0100 features variable protections like hysteresis) Thermal Shutdown (TSD), Vcc Under voltage Vcc Under Voltage Lockout with Hysteresis Lockout (UVLO), Over Load Protection (OLP), (UVLO) Over Voltage Protection (OVP). Over Voltage Protection The HFC0100 is available in the 8-pin SOIC8 Over Load Protection. package.
