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 R
SET
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

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
R
SET
pin current, applying a PWM signal on the
Control signals, or adding a switched resistor in
parallel with R
SET
. 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.
