MP3394 The Future of Analog IC Technology Step-up, 4-String Max 200mA/String White LED Driver DESCRIPTION The MP3394 is a step-up controller with 4channel current sources designed for driving the WLED arrays for large size LCD panel backlighting applications. The MP3394 is flexible for extending LED channels with two or more MP3394s in parallel while operating from a single inductor power source. The MP3394 uses current mode, fixed frequency architecture. The switching frequency is programmable by an external frequency setting resistor. It drives an external MOSFET to boost up the output voltage from a 5V to 28V input supply. The MP3394 regulates the current in each LED string to the programmed value set by an external current setting resistor. The MP3394 applies 4 internal current sources for current balance and the current matching can achieve 2.5% regulation accuracy between strings. Its low 350mV regulation voltage on LED current sources reduces power loss and improves efficiency [ … ]
