General Description

The MIC2299 is a high power boost-switching regulator that is optimized for constant-current control.

The MIC2299 is capable of driving up to 2 series 1A white LED for photoflash and other applications.

The feedback voltage is only 200mV, minimizing power dissipation in constantcurrent control applications, and hence extends battery life.

Overview

MIC2299 3.5A Minimum, 2MHz High Brightness LED Driver General.

Key Features

  • Programmable current control.
  • 200mV ±10% feedback voltage.
  • 2.5V to 10V input voltage.
  • Output over-voltage protection (OVP).
  • Output voltage up to 30V (max).
  • Fixed 2MHz Operation.
  • Guaranteed 3.5A switch current over-temperature.
  • Solution size of just 0.25in2 (1.6cm2).
  • Output power range of 7W to 12W.
