CAT3643
3-Channel Ultra High
Efficiency Quad-Mode ) LED
Driver
Description
The CAT3643 is a high efficiency Quad ? Mode ? fractional charge
pump that can drive up to three LEDs programmable by a one wire
digital interface. The inclusion of a 1.33x fractional charge pump
mode increases device efficiency by up to 10% over traditional 1.5x
charge pumps with no added external capacitors.
Low noise input ripple is achieved by operating at a constant
switching frequency which allows the use of small external ceramic
capacitors. The multi ? fractional charge pump supports a wide range of
input voltages from 2.4 V to 5.5 V.
The EN/DIM logic input functions as a chip enable and a digital
dimming interface for current setting of all LEDs. Six different current
ratios are available via the interface.
The device is available in the 16 ? pad TQFN or 12 ? pad TDFN 3 mm
x 3 mm package with a max height of 0.8 mm.
ON Semiconductor ’s Quad ? Mode ? 1.33x charge pump switching
architecture is patented.
