Monolithic power switch regulator

Technology Cover
发布日期: 2023-02-28, ON Semiconductor

The MC34163 series is a monolithic power switch regulator that contains the main features required for a dc-to-dc converter. The series is designed specifically for boost, step-down and voltage inverter applications with a minimum number of external components. These devices include two high-gain voltage feedback comparators, temperature compensation references, control duty ratio oscillators, drivers with bootstrap capabilities for increased efficiency, and a high-current output switch.
