CAT3647 - 3-Channel Ultra High Efficiency LED Driver with 32 Dimming Levels
ON Semiconductor
Description
The CAT3647 is a high efficiencye 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 setting the current in all the LED channels. The
1−wire pulse−dimming interface supports 32 linear steps from
full−scale down to zero current.
The device is available in the tiny 16−pad TQFN 3 mm x 3 mm
package with a max height of 0.8 mm.
ON Semiconductor’s 1.33x, charge pump switching architecture is
patented.
