MP1519中文资料Charge Pump 4-Channel WLED Driver数据手册MPS规格书
MP1519规格书详情
描述 Description
The MP1519 is a fully automatic driver for powering four white LEDs, with up to 4V forward voltage, from a single Li-Ion or three NiMH cells. The driver performs all of the sensing and control to run the LEDs at an optimum charge pump ratio for efficiency without an expensive inductor. The driver allows PWM operation to support brightness control. The tiny 3mm x 3mm QFN16 package and small external capacitors allow for the most compact white LED solution available.
