CAT3604A  
4-Channel Regulated  
Charge Pump White LED  
Driver  
Description  
http://onsemi.com  
The CAT3604A is a charge pump operating in either 1x (LDO)  
mode or 1.5x fractional mode regulating current through each of the 4  
LED pins. Operation at a fixed high frequency of 1 MHz typical  
allows the use of very small value ceramic capacitors.  
The CAT3604A drives white light-emitting diodes (LEDs)  
connected in parallel and provides tightly matched regulated current to  
achieve uniformity of brightness in LCD backlighting applications.  
TQFN16  
HV4 SUFFIX  
CASE 510AE  
An external resistor R  
controls the output current level. LED  
SET  
currents of up to 30 mA are supported over a range of input supply  
voltages from 3 V to 5.5 V, making the device ideal for  
battery-powered applications.  
PIN CONNECTIONS (Note 1)  
LED dimming can be accomplished by several methods including  
using a DC voltage to set the RSET pin current, applying a PWM  
signal on the Control signals, or adding a switched resistor in parallel  
with RSET. The Enable input pin allows the device to be placed in  
power-down mode with “zero” quiescent current.  
The CAT3604A features short circuit and overcurrent limiting  
protection. The device is available in a 16pad TQFN package with a  
max height of 0.8 mm.
