DESCRIPTION

The CAT3604 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 1MHz typical allows the

use of very small value ceramic capacitors.

The CAT3604 drives white light-emitting diodes

(LEDs) connected in parallel and provides tightly

matched regulated current to achieve uniformity of

brightness in LCD backlighting applications. An

external resistor RSET controls the output current

level. LED currents of up to 30mA are supported

over a range of input supply voltages from 3V to

FEATURES

I Drives individually up to 4 LEDs

I Output current up to 30mA per LED

I Digital control On/Off of each LED

I Compatible with supply voltage of 3V to 5.5V

I Power efficiency up to 93%

I 2 modes of operation 1x and 1.5x

APPLICATIONS

I Color LCD and keypad Backlighting

I Cellular Phones

I Handheld Devices

5.5V, making the device ideal for battery-powered

applications.

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 CAT3604 features short circuit and overcurrent

limiting protection. The device is available in a 16-

lead thin QFN package with a max height of 0.8mm.

I Digital Cameras

I PDAs

I Portable MP3 players
