1 / 14 page © Semiconductor Components Industries, LLC, 2010 May, 2010 − Rev. 7 1 Publication Order Number: CAT3636/D CAT3636 6-Channel Quad-Mode[ Fractional LED Driver in TQFN 3x3 Description The CAT3636 is a high efficiency Quad−Mode fractional charge pump that can drive up to six 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 2.5 V to 5.5 V. The EN/SET logic input functions as a chip enable and a “1−wire” addressable interface for control and current setting of all LEDs. Three groups of two LEDs can be configured with independent LED currents between 0.25 mA and 32 mA. The device is available in a tiny 16−lead TQFN 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.
