SP7686 - Constant Current Flash Driver

Datasheet Summary

Description

The SP7686 is a current regulated charge pump ideal for powering high-brightness LEDs for camera FLASH applications of up to 500mA.

The charge pump automatically switches between step-up and step-down modes ensuring that the LED current does not depend on the forward voltage.

Features

  • Output current up to 500mA Up to 94% efficiency in 1x mode Built-in LED current setting DAC One line serial interface 2.4MHz switching frequency FB Reference voltage adjusts in 10mV steps from 60mV to 360mV DAC signal shutdown control Power-saving shutdown mode of 10nA PWM brightness control for DAC Fast turn-on (.
