General Description

AIC1647 is a fixed frequency step-up DC/DC converter designed to drive white LEDs with a constant current to provide backlight in handheld devices.

Series connection of the LEDs provides identical LED currents resulting in uniform brightness.

This configuration eliminates the need for ballast resistors.

Key Features

  • 1.2MHz Fixed Frequency Current-Mode PWM Operation. Efficiency Up to 84% at VIN=4.2V, 3LEDs, ILED=20mA Drives Up to 6LEDs in series Low Supply Current: 70µA Matches LED Current Require Tiny Inductors and Capacitors Tiny TSOT-23-5, and SOT-23-5 Packages.
