RAA230222 - Dual Step-Down DC/DC Converter

Download the RAA230222 datasheet PDF. This datasheet also covers the RAA230221 variant, as both devices belong to the same dual step-down dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General 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.
