BMP390L

The MP3900DK is a boost controller that drives an external MOSFET capable of handling 10A current. It has an operational current of typically 180µA and can accommodate off-line, Telecom and non-isolated applications. Internal undervoltage lockout, slope compensation and peak current limiting are all provided to minimize the external component count. In a boost application, with an output voltage of less than 30V, 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 MP3900DK can also be used for other topologies including Forward, Flyback and Sepic. The 10V gate driver voltage minimizes the power loss of the external MOSFET while allowing the use of a wide variety of standard threshold devices.  The MP3900DK is available in 8-pin MSOP and SOIC packages.
