MP3394S - Max 200mA/String White LED Driver

General Description

The MP3394S is a step-up controller with 4 current channels.

It’s designed to drive WLED arrays for large-size LCD-panel backlighting applications.

The MP3394S is flexible, and can expand the number of LED channels with 1 or 2 MP3394S in parallel operating from a single inductive power source.

The Future of Analog IC Technology MP3394S Step-Up, 4-String Max 200mA/String White LED Driver DESCRIPTION The MP3394S is a step-up controller with 4 current channels. It’s designed to drive WLED arrays for large-size LCD-panel backlighting applications. The MP3394S is flexible, and can expand the number of LED channels with 1 or 2 MP3394S in parallel operating from a single inductive power source. The MP3394S uses an architecture of current – mode and fixed operation frequency The frequency is programmable by an external frequency-setting resistor. MP3394S drives an external MOSFET to boost up the output voltage from a 5V to 28V input supply. It regulates the current in each LED string to the programmed value set by an external currentsetting resistor.
