Overview

Product Highlight

  • Supply Voltage: 2.5 to 10 V
  • Output Current per Channel: 20 mA
  • Output Voltage: 40 V
  • Switching Frequency-Max: 600 kHz
The MIC2297-42YML TR is a 600 KHz PWM boost switching regulator optimized for driving 6-10 series white LEDs. Available in surface mount MLF-10 package.

The MIC2297 implements constant frequency 600 KHz PWM control. The high frequency PWM operation saves board space by reducing external component sizes. The added benefit of the constant frequency PWM operation is much lower noise and input ripple injected back to the battery source than with variable frequency topologies.

Features:

  • 2.5 V to 10 V input voltage range
  • Output voltage up to 40 V
  • 1.2 A switch current
  • 600 KHz PWM operation
  • Trimmed 200 mV feedback voltage
  • Output over voltage protection (fixed or adjustable)
  • PWM Brightness Control
  • DAC Brightness Control
  • <1% line regulation
  • 1 µA shutdown current
  • Over temperature protection
  • UVLO
  • 2.5 mm x 2.5 mm MLF-10L package
  • –40 oC to +125 oC junction temperature range

Applications:

  • PDAs
  • GPS systems
  • Smart phones
  • Mini PCs
  • Digital cameras
  • IP phones
  • LED flashlights
