HF500-30 Overview
The HF500-30 is a fixed-frequency, currentmode regulator with built-in slope pensation. The HF500-30 bines a 700V MOSFET and a full-featured controller into one chip for a lowpower, offline, flyback, switch-mode power supply. At medium and heavy loads, the regulator works in a fixed frequency with frequency jittering.
