Overview
CAT3616
6-Channel Charge Pump LED Driver with EZDimt
Description
The CAT3616 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 up to 91%, and is ideal for Li−Ion battery powered devices.
Two groups of LEDs, main (MAIN1 to MAIN4) and sub (SUB1 and SUB2) are progr...
