DESCRIPTION
The CAT36
1
6 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 1MHz which allows
the use of small external ceramic capacitors. The
1x/1.5x fractional charge pump supports a wide range
of input voltages from 3V to 5.5V 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
ˉˉˉ
(active low) and ENS
inputs. Independent
current from 1mA to 31mA with a 1mA 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-lead thin QFN package
with a max height of 0.8mm.
