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