The HFC0100 is a peak current mode controller with green mode operation. It offers high efficiency across the entire line and load ranges, and meets stringent worldwide energy efficiency requirements.
The device integrates a high-voltage current source, and valley detection ensures a minimum drain-source voltage switching (quasi-resonant operation). If the output power drops below a set level, then the controller enters burst mode.
Full protection features include thermal shutdown, VCC under-voltage lockout (UVLO) protection, overload protection (OLP), and over-voltage protection (OVP).
The HFC0100 is available in a compact SOIC-8 package.
