CAT4237 High Voltage CMOS Boost White LED Driver

CAT4237 Description

www.DataSheet4U.com 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.

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

CAT4237 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. LED dimming can be done by using a DC voltage, a logic signal, or a pulse width modulation (PWM) signal. The shutdown input pin allows
