Product Detail

The MP3908 is a flexible current-mode PWM controller optimized for power-supply applications.?The MP3908 features resistor-programmable dead-time control to optimize efficiency for a broad number of different configurations, and a synchronous secondary gate drive.?The MOSFET drivers are capable of driving 10A MOSFETs. It has an operational current of typically 270? and can accommodate off-line, Telecom and non-isolated applications. Under-voltage lockout, soft start, slope compensation and peak current limiting are all included. In a boost application, with an output voltage of less than 28V, the current sense pin can connect directly to the drain of the external switch. This eliminates the requirement for an additional current sensing element and its associated efficiency loss.?While designed for boost applications, the MP3908 can also be used for other topologies including Forward, Flyback and Sepic. The 10V gate driver compliance minimizes the power loss of the external MOSFET while allowing the use of a wide variety of standard threshold devices. An externally programmable delay following the turn off of the synchronous rectifier allows the incorporation of secondary side synchronous rectifier.?The MP3908 is available in space saving 10-pin MSOP package.
