MP3378 LED Lighting Drivers

Monolithic Power Systems (MPS) MP3378 LED Lighting Drivers deliver a one-chip solution for monitor applications and feature a step-up controller with four current channels for backlighting. A high-efficiency buck converter is used for internal bus voltage or standby power. An external MOSFET is driven by a four-string WLED controller to boost up the output voltage from the input supply. This regulates the current in each LED string to the programmed value. MPS MP3378 LED Lighting Drivers integrate rich protection modes, including LED short / open protection, and inductor / diode short protection. Applications include desktop LCD flat-panel displays, flat-panel video displays, and 2D/3D LCD TVs and monitors.
