General Description

The CP2122 is a step-up DC/DC converter specifically designed for driving white LEDs with a constant current.

Operation at a fixed switching frequency of 1.4MHz allows the device to be used with small value external ceramic capacitors and inductors.

Series connection of LEDs provides equal LED current which results in uniform brightness.

Key Features

  • an internal soft start to eliminate inrush current during startup. Equipped with built-in over-voltage protection function, the device enters a very low power operating mode during the “OPEN LED” fault conditions. The CP2122 is available in SOT23-5L package. SOT23-5L -40℃~85℃ Features y y y y y y y y Switch current limit 700mA Drives LED strings up to 34V Up to 84% efficiency Soft start “in-rush” current limiting Fast 1.4 MHz switching frequency Built-in over-voltage protection Shutdown curren.
