CAT3612 Programmable 300 mA Camera Flash LED Driver Description The CAT3612 is a high−efficiency 1x/1.5x fractional charge pump 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. Low noise operation 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 90%, and is ideal for Li−Ion battery powered devices. The EN/DIM logic input provides a 1−wire EZDimt interface for dimming control of the LEDs.
