Catalyst Semiconductor CAT3636 Datasheet
The CAT3636 is a high‑efficiency quad‑mode fractional charge‑pump LED driver that can drive up to six LEDs with programmable currents via a one‑wire digital interface. It operates from 2.5 V to 5.5 V input, provides up to 92 % power efficiency, and includes features such as soft‑start, current limiting, short‑circuit and thermal‑shutdown protection.
Typical applications include LCD backlights, RGB LEDs, cellular phones, digital cameras and other handheld devices. Ordering information, pin configuration, electrical characteristics and timing diagrams are provided for designers, and the device is supplied in a 3 mm × 3 mm 16‑lead TQFN package.
