Renesas RAA230153

28.0V Input, Step-Down DC/DC Converter + Battery Backup

Overview

TopologyBuck Converter
Input voltage7-28 V
Output 16 V / 3 A
IC revision1.0

Description

The RAA23014x and RAA23015x are 1CH step-down DC/DC converter, 7V to 28V input voltage range. Auto PFM mode makes devices low power operation at light load, so it makes a system lower power.The RAA23014x is suitable for battery backup system using lithium primary cell with built-in battery backup circuit.
