HFC0500GS - Fixed Frequency Flyback Controller

Download the HFC0500GS datasheet PDF. This datasheet also covers the HFC0500 variant, as both devices belong to the same fixed frequency flyback controller family and are provided as variant models within a single manufacturer datasheet.

General Description

HFC0500 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.

HFC0500 is a green-mode highly efficient controller.

Key Features

  • multiple protections that include thermal shutdown (TSD), VCC undervoltage lockout (UVLO), overload protection (OLP), over-voltage protection (OVP), and brown-out protection. HFC0500 is available in an SOIC8-7A package.

HFC0500 Fixed Frequency Flyback Controller with Ultra-low No Load Power Consumption The Future of Analog IC Technology DESCRIPTION HFC0500 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. 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.
