XYSemi XR3403

1.2 MHz, 26V Step-up DC/DC Converter

Overview

TopologyBoost Converter
Input voltage2.3-6 V
Switching frequency900-1500 kHz
Output 126 V / 3 A
IC revision0.6

Description

The XR3403 is a high frequency, high efficiency DC to DC converter with an integrated 3A, 0.1Ω power switch capable of providing an output voltage up to 26V. 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.
