6 Watt Boost LED Driver

The CAT4240 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 current set by the external resistor R1. The CAT4240 High-Voltage output stage is perfect for driving mid-size and large panel Displays containing up to ten white LEDs in series.
