可编程300mA 相机闪光LED驱动器

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 150mA and make CAT3612 ideal for driving one or two flash LEDs.

Low noise operation 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 90%, and is ideal for Li-Ion battery powered devices.

The EN/DIM logic input provides a 1-wire EZDim™ interface for dimming control of the LEDs. When enabled, pulsing the EN/DIM reduces the LED current on each negative edge in 31 linear steps from 150mA down to zero current.

The device is available in the tiny 12-lead thin DFN 3mm x 3mm package with a max height of 0.8mm.
