Overview: CAT3614 4-Channel 1-Wire LED Driver in 3 x 3 mm Package.

General Description

The CAT3614 is a high efficiency 1x/1.5x fractional charge pump with programmable dimming current in four LED channels.

To ensure uniform brightness in LCD backlight applications, each LED channel delivers an accurate regulated current.

Low noise and input ripple is achieved by operating at a constant switching frequency of 1 MHz which allows the use of small external ceramic capacitors.
