General Description

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 1 MHz allows the device to be used with small value external ceramic capacitors and inductor.

LEDs connected in series are driven with a regulated current set by the external resistor R1.
