CAT4240  
6 Watt Boost LED Driver  
FEATURES  
DESCRIPTION  
„ Switch Current Limit 750mA  
The CAT4240 is a DC/DC step-up converter that delivers  
an accurate constant current ideal for driving LEDs.  
Operation at a fixed 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. The CAT4240 high-voltage output stage is perfect for  
driving mid-size and large panel displays containing up to  
ten white LEDs in series.  
„ Drives High Voltage LED strings (38V)  
„ Up to 94% Efficiency  
„ Low Quiescent Ground Current 0.6mA  
„ 1MHz Fixed Frequency Low noise Operation  
„ Soft start “in-rush” current limiting  
„ Shutdown current less than 1μA  
„ Open LED Overvoltage Protection  
„ Automatic Shutdown at 1.9V (UVLO)  
„ Thermal overload protection  
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.  
„ Thin SOT23 5-Lead (1mm max height)  
APPLICATIONS  
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.  
„ GPS Navigation Systems  
„ Portable Media Players  
„ Handheld Devices, Digital Cameras
