CAT3614
4-Channel 1-Wire LED
Driver in 3 x 3 mm Package
Description
The CAT3614 is a high efficiency 1x/1.5x fractional charge pump
VIN
VOUT
with programmable dimming current in four LED channels. To ensure
uniform brightness in LCD backlight applications, each LED channel
delivers an accurate regulated current.
Low noise and input ripple is achieved by operating at a constant
switching frequency of 1 MHz which allows the use of small external
ceramic capacitors. The 1x/1.5x fractional charge pump supports a
wide range of input voltages from 3 V to 5.5 V with efficiency up to
91%, and is ideal for Li ? Ion battery powered devices.
The EN/DIM logic input provides a 1 ? wire EZDim t interface for
dimming control of the LEDs. When enabled, a series of clock pulses
reduces the LED brightness in 1 mA steps on each negative going
edge. Currents from 0 mA to 31 mA are supported.
The device is available in the tiny 12 ? pad TDFN 3 x 3 mm package
with a max height of 0.8 mm.
