DESCRIPTION
The CAT3603 is a charge pump LED driver
operating in either 1x (LDO) mode or 1.5x fractional
mode regulating current through each of the 3 LED
pins. Operation at a constant switching frequency of
1MHz allows the use of very small value ceramic
capacitors.
The CAT3603 drives 3 white LEDs in parallel and
provides tightly matched regulated current to achieve
uniform brightness in LCD backlighting applications.
An external resistor, RSET, controls the output
current level. The device can deliver up to 30mA over
an input voltage supply range from 3V to 5.5V,
making it ideal for battery-powered applications
LED dimming can be accomplished using several
methods; using a DC voltage to set the RSET pin
current, applying a PWM signal on the EN pin, or
adding a switched resistor in parallel with RSET. The
EN input pin allows the device to be placed in power-
down mode with “near-zero” quiescent current.
The device is available in the tiny 12-lead thin DFN
3mm x 3mm package with a max height of 0.8mm.
