CAT37

CMOS White LED Driver

Boost Converter

Description

The CAT37 is a DC/DC step up converter that delivers a regulated

output current. Operation at a constant switching frequency of

1.2 MHz allows the device to be used with very small value external

inductor and ceramic capacitors.

http://onsemi.com

The CAT37 is targeted to drive multiple white light−emitting diodes

(LEDs) connected in series and provides the necessary regulated current

to control the brightness and the color purity. An external resistor R1

controls the output current level. LED currents of up to 40 mA can be

supported over a wide range of input supply voltages from 2.5 V to 7 V,

making the device ideal for battery−powered 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−down mode with “near zero”

quiescent current.

In addition to overcurrent limiting protection, the device also

includes detection circuitry to ensure protection against open−circuit

load fault conditions.

The device is available in a low profile (1 mm max height) 5−lead

TSOT−23 package.
