CAT3637 - 6-Channel Programmable High Efficiency LED Driver
ON Semiconductor
Description
The CAT3637 is a high efficiency fractional charge pump that can
drive up to six LEDs programmable by a 1−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 2.5 V to 5.5 V.
The EN/SET logic input functions as a chip enable and a digital
programming interface for setting the current in the LED channels.
The 1−wire pulse−programming interface supports 15 linear steps
from zero current to 30 mA full−brightness in 2 mA steps.
The device is available in a tiny 16−pad TQFN 3 x 3 mm package
with a maximum height of 0.8 mm.
ON Semiconductor’s 1.33x, charge pump switching architecture is
patented.
