General Description

The MIC3289 is a PWM boost-switching regulator that is optimized for constant-current white LED driver applications.

The MIC3289

Overview

www.DataSheet4U.com MIC3289 1.2MHz PWM White LED Driver with Internal Schottky Diode and True 1-Wire Digital Control PRELIMINARY INFORMATION.

Key Features

  • an internal Schottky diode, allowing an efficient DC/DC solution that requires only 4 external components. The MIC3289 allows for a single wire simple digital interface to control the dimming over 16 steps with a log scale to give better resolution at the lower currents to better match the sensitivity of the human eye The feedback voltage of the MIC3289 is only 250mV, allowing high efficiency while retaining excellent accuracy for the white LED current. The MIC3289 implements a constant frequenc.
