Monolithic Power Systems (MPS) HFC0100 Quasi-Resonant Controller
Monolithic Power Systems (MPS) HFC0100 Quasi-Resonant Controller is a peak current-mode controller with green mode operation. It offers high efficiency across the entire line and load range and meets stringent worldwide energy efficiency requirements.
The HFC0100 is integrated with a high-voltage current source, and its valley detector ensures minimum drain-source voltage switching (quasi-resonant operation). The controller enters burst mode when the output power falls below a set level.
The HFC0100 features protection features, including thermal shutdown (TSD), VCC undervoltage lockout (UVLO), overload protection (OLP), and over-voltage protection (OVP). The Monolithic Power Systems (MPS) HFC0100 is available in a compact SOIC-8 package.
