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 programmable through the ENM (active low) and ENS

inputs. Independent current from 1 mA to 31 mA with a 1 mA step are

set by toggling the ENM and ENS inputs. The enable EN input pin

allows to shutdown the device with zero quiescent current.

The device is available in a 16−pad TQFN package with a max

height of 0.8 mm.
