ZXSC400EV7 USER GUIDE

Overview

TopologyBoost Converter
Input voltage1.8-3 V
Output 10.7 A
IC revision2

Description

The ZXSC400 is a voltage mode boostconverter in a SOT23-6 package. The lowfeedback voltage VFB input allows thecurrent in a chain of LEDs to be setaccurately. The ZXSC400EV7 is designed todrive one or two 3W LEDs at a constantcurrent of 700mA from an input voltagebetween 1.8V and 3.0V. The board is fittedwith a socket for use with a variety of LEDtypes. The board is open-circuit-LEDprotected and intended to be used with twoalkaline, NiCad or NiMH batteries.

Features

  • Drives one or two 3W LEDs.
  • Typical efficiency of 80%.
  • Open-circuit-LED protected.
  • High-sided current sensing.
  • Compatible with Future LED boards.

Typical applications

  • Portable illumination
  • LED torches and flashlights
  • Emergency lights
