BM0123A - Inherently Matched LED Current driver chip

General Description

The BM0123A is a step-up DC/DC converter specifically designed to drive up to 5 series white LEDs with constant current.

Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminates the need for ballast resistors.

Key Features
