HFC0500 is a fixed-frequency current-mode controller with internal slope compensation.

Product Detail

HFC0500 is a fixed-frequency current-mode controller with internal slope compensation. It is specifically designed for the medium-power, off-line, flyback, switch-mode power supplies. HFC0500 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. HFC0500 offers frequency jittering to help dissipate energy generated by conducted noise. HFC0500 employs overpower compensation function to narrow the difference of over power protection point between low line and high line. HFC0500 also has X-cap discharge function to discharge the X-cap when the input is unplugged. This aids in lowering no load power. HFC0500 features multiple protections that include thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), over-voltage protection (OVP), and brown-out protection. HFC0500 is available in an SOIC8-7A package.
