CAT4237  
High Voltage CMOS Boost White LED Driver  
FEATURES  
DESCRIPTION  
„ 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 Switch  
„ Shutdown current less than 1µA  
„ Open LED low power mode  
„ Automatic Shutdown at 1.9V (UVLO)  
„ Thermal shutdown protection  
„ RoHS-compliant  
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  
1MHz 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 40mA  
can be supported over a wide range of input supply  
voltages from 2.8V to 5.5V, 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.  
„ Thin SOT23 5-Lead (1mm max height)  
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 “zero” quiescent current.  
APPLICATIONS  
„ Color LCD and keypad Backlighting  
„ Cellular Phones  
„ Handheld Devices  
„ Digital Cameras  
In addition to thermal protection and overload current  
limiting, the device also enters a very low power operating  
mode during “Open LED” fault conditions. The device is  
housed in a low profile (1mm max height) 5-lead thin  
SOT23 package for space critical applications.  
„ PDAs  
„ Portable Game Machine
