The HT68F03C is an 8-pin SOP-150mil RoHS-compliant integrated circuit manufactured by Holtek. It is a high-speed dual-channel, high-side, low-side PWM controller IC with built-in control and safety protection functions. It is designed to provide highest efficiency conversion of DC power sources into regulated DC outputs in several types of DC-DC converters. The HT68FONC features dual PWM controllers, overvoltage protection, undervoltage protection, overcurrent protection, short-circuit protection and over-temperature protection. Other features include soft-start and shut-down control, passive-mode control, automatic mode selection, dynamic input voltage scaling, and frequency synchronization. It also supports multiple output regulation modes.
