Drives up to 5 White LEDs from 3V  
The CAT4137 is a DC/DC step-up converter that  
delivers a regulated output current. Operation at  
a constant switching frequency of 1MHz allows  
the device to be used with small value external  
ceramic capacitors and inductor.  
Power Efficiency up to 87%  
Low Quiescent Ground Current 0.1mA  
Adjustable Output Current (up to 30mA)  
High Frequency 1MHz Operation  
“Zero” current shutdown mode  
Operates down to 2V (from two AA batteries)  
Soft start power-up  
The device drives a string of white LEDs  
connected in series and provides the regulated  
current to control the LEDs with inherent uniform  
brightness and matching. An external resistor R1  
sets the output current and allows up to 30mA  
current to be supported over a wide range of  
input supply voltages from 2.2V to 5.5V, making  
the device ideal for battery-powered applications.  
Open LED low power mode  
Automatic shutdown at 1.9V (UVLO)  
Thermal shutdown protection  
Thin SOT23 5-Lead (1mm max height)  
Applications  
LED dimming can be done by using a DC  
voltage, a logic signal, or a pulse width  
modulation (PWM) signal. The shutdown control  
pin allows the device to be placed in power-down  
mode with “zero” quiescent current.

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.
