ft3356 Description
The ft3356 is a low noise, high efficiency 6-channel charge-pump LED driver that uses a quad-mode load switch: pass-through (1X), fractional (1.33X/1.5X), or doubling (2X) conversion to maximize efficiency for white LED applications. The ft3356 is capable of driving 6 LED channels from a 2.7V to 5.5V input.
