CAT4139 Datasheet - ON 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 1 MHz allows the device to be used with small value external ceramic capacitors and inductor. LEDs connected in series are driven with a reg.

CAT4139 Features

* Switch Current Limit 750 mA

* Drives LED Strings up to 22 V

* Up to 87% Efficiency

* Low Quiescent Ground Current 0.6 mA

* 1 MHz Fixed Frequency Low Noise Operation

* Soft Start “In

* rush” Current Limiting

* Shutdown Current Less than 1 mA

* Open LED Overvolt
