MC33167 Datasheet Step-up/down/inverting Switching Regulators

Manufacturer: onsemi

Overview: DATA SHEET www.onsemi.com Inverting Switching Regulators - Step-Up/Down 5.0 A MC34167, MC33167 The MC34167, MC33167 series are high performance fixed frequency power switching regulators that contain the primary functions required for dc−to−dc converters. This series was specifically designed to be incorporated in step−down and voltage−inverting configurations with a minimum number of external components and can also be used cost effectively in step−up applications. These devices consist of an internal temperature compensated reference, fixed frequency oscillator with on−chip timing components, latching pulse width modulator for single pulse metering, high gain error amplifier, and a high current output switch.
