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.
