Renesas RAA230121

16V Input, 3A, Step-Down DC/DC Converter

Overview

TopologyBuck Converter
Input voltage4.5-16 V
Output 13.3 V / 3 A
IC revision1

Description

The RAA23012x and RAA23013x are 1CH step-down DC/DC converter, 4.5V to 16V input voltage rage and 3Aoutput current. Auto PFM mode makes devices low power operation at light load, so it makes a system lowerpower.The RAA23012x is suitable for battery backup system using lithium primary cell with built-in battery backupcircuit.

Features
