HF500-15 Overview
The HF500-15 is a fixed-frequency, currentmode regulator with built-in slope pensation. It bines a 700V MOSFET of high avalanche ruggedness and a full-featured controller into one chip for a low-power, offline, flyback, switch-mode power supply. At medium and heavy loads, the regulator works in a fixed frequency with frequency jittering, which helps to spread energy out in a conducted mode.
