CAT37 CMOS White LED Driver

CAT37 Description

CAT37 CMOS White LED Driver Boost Converter .
The CAT37 is a DC/DC step up converter that delivers a regulated output current.

CAT37 Features

* Low Quiescent Ground Current (0.5 mA Typical)
* Power Efficiency Over 80%
* Compatible Pinout with LT1937
* Adjustable Output Current (up to 40 mA)
* High Frequency 1.2 MHz Operation
* Input Voltage Operation down to 2.5 V
* Low Resistance (0

CAT37 Applications

* A high voltage output stage allows up to 4 White LEDs to be driven in series. Series drive provides inherent current matching. 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 the device to be placed in power
