RAA230231 - Dual Step-Down DC/DC Converter

This page provides the datasheet information for the RAA230231, a member of the RAA230221 Dual Step-Down DC/DC Converter family.

Description

The RAA23022x and RAA23023x are dual step-down DC/DC converter, 4.5V to 16V input voltage rage and 3A output current.

Auto PFM mode makes devices low power operation at light load, so it makes a system lower power.

Features
