Overview

HFC0500GS-Z is a fixed-frequency current-mode controller with internal slope compensation. It is specifically designed for the medium-power, offline, flyback, switch-mode power supplies. HFC0500GS-Z is a green-mode highly efficient controller. At light loads, the controller freezes the peak current and reduces its switching frequency down to 25kHz to offer excellent light-load efficiency. At very light loads, the controller enters burst mode to achieve very low standby power consumption.HFC0500GS-Z offers frequency jittering to help dissipate energy generated by conducted noise.HFC0500GS-Z employs overpower compensation function to narrow the difference of over power protection point between low line and high line.HFC0500GS-Z also has X-cap discharge function to discharge the X-cap when the input is unplugged. This aids in lowering no load power.HFC0500GS-Z features multiple protections that include thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), over-voltage protection (OVP), and brown-out protection.HFC0500GS-Z is available in an SOIC8-7A package.
