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.
The MP3394S applies 4 internal current sources for current balance.
The current matching can achieve 2.5% regulation accuracy between
strings. Its low regulation voltage on LED current sources reduces
power loss and improves efficiency.
An external PWM input signal or DC input signal controls PWM
dimming. In DC-input dimming mode, the dimming PWM signal can be
generated internally and the dimming frequency is programmed by an
external setting capacitor.
