CAT3612
Programmable 300 mA
Camera Flash LED Driver
Description
with programmable current in two LED channels. Each channel
delivers accurate regulated current up to 150 mA and make CAT3612
ideal for driving one or two flash LEDs.
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
90%, and is ideal for Li−Ion battery powered devices.
dimming control of the LEDs. When enabled, pulsing the EN/DIM
reduces the LED current on each negative edge in 31 linear steps from
150 mA down to zero current.
