6-Channel Charge Pump
LED Driver with EZDimt
Description
with programmable dimming current in six LED channels. To ensure
uniform brightness in LCD backlight applications, each LED channel
delivers an accurate regulated current.
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.
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.
