CAT3616
6-Channel Charge Pump
LED Driver with EZDim t
Description
The CAT3616 is a high efficiency 1x/1.5x fractional charge pump
TAB
is
GND
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.
