CAT4237 - White LED Driver, CMOS Boost Converter, High Voltage
ON Semiconductor
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. LED currents up to 40 mA can be supported over a wide range of input supply voltages from 2.8 V to 5.5 V, making the device ideal for battery−powered applications. The CAT4237 high−voltage output stage is perfect for driving six, seven or eight white LEDs in series with inherent current matching in LCD backlight applications.
