About This Product

■Summary

The MP3900 is a boost controller that drives an external MOSFET that can handle 10A of current. Operating current is typically 180 µA for offline, telecommunications, and non-isolated applications. Internal undervoltage lockout, slope compensation, and peak current limiting are all provided to minimize external component count. For boost applications with output voltages less than 30V, the current sense pin can be connected directly to the drain of an external switch. This eliminates the need for additional current sensing elements and the associated efficiency loss. The MP3900 is designed for boost applications, but can also be used in other topologies such as forward, flyback, and SEPIC. The 10V gate driver voltage minimizes external MOSFET power dissipation while allowing the use of devices with a variety of standard thresholds. The MP3900 is available in 8-pin MSOP and SOIC packages.
