Product details

Description

The CAT3626 is a high efficiency 1x/1.5x fractional charge pump with programmable dimming current in six 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.The 1x/1.5x fractional charge pump supports a wide range of input voltages from 3 V to 5.5 V with efficiency u
