CAT3636 Datasheet 6-channel Led Driver

Manufacturer: Catalyst Semiconductor

Overview: www.DataSheet4U.com CAT3636 6-Channel Quad-ModeTM Fractional LED Driver in.

General 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.
