1.2MHZ,14V Step-up DC/DC Converter

Overview

TopologyBoost Converter
Input voltage2.3-6 V
Switching frequency900-1500 kHz
Output 15 V
IC revision0.3

Description

The XR3403D is a high frequency, high efficiency DC to DC converter with an integrated 4A, 0.1Ω power switch capable of providing an output voltage up to 14V. The fixed 1.2MHz allows the use of small external inductions and capacitors and provides fast transient response. It integrates Soft start, Comp,. only need few components outside. It can be adjusted SW current limit by one resistor or analog voltage
