CAT4237 Datasheet - Catalyst Semiconductor

CAT4237 High Voltage CMOS Boost White LED Driver

The CAT4237 is a DC/DC step-up converter that delivers an accurate constant current ideal for driving LEDs. Operation at a constant 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.

CAT4237 Features

* Drives 6 to 8 White LEDs in series from 3V Up to 87% Efficiency Low Quiescent Ground Current 0.6mA Adjustable Output Current (up to 40mA) High Frequency 1MHz Operation High Voltage Power Swi
