CAT4238 - High Efficiency 10 Led Boost Converter

The CAT4238 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
