Applications
* The MP3384 uses current mode, fixed frequency architecture. The switching frequency can be selected at 1.25MHz or 625kHz. It generates an output voltage up to 50V from a 4.5V to 25V input supply. The MP3384 independently regulates the current in each LED string to the user programmed value set by a
