CAT4139 Datasheet - Catalyst Semiconductor

CAT4139 22V High Current Boost White LED Driver

The CAT4139 is a DC/DC step-up converter that delivers an accurate constant current ideal for driving LEDs. Operation at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor. LEDs connected in series are driven with a regulated cu.

CAT4139 Features

* Switch Current Limit 750mA Drives LED strings up to 22V Up to 87% Efficiency Low Quiescent Ground Current 0.6mA 1MHz Fixed Frequency Low noise Operation Soft start “in-rush” current limiting
