UMC33167中文资料5.0A, STEP-UP/DOWN/ INVERTING  SWITCHING REGULATORS数据手册UTC规格书

描述 Description

The UTC UMC33167 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-upapplications. These devices consist of an internal temperature compensatedreference, 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.
