1.5A, 15V, 800KHz, Synchronous Buck Converter



The MP2106 is a 1.5A, 800KHz synchronous buck converter designed for low voltage applications requiring high efficiency. It is capable of providing output voltages as low as 0.9V, and integrates top and bottom switches to minimize power loss and component count. The 800KHz switching frequency reduces the size of filtering components, further reducing the solution size. The MP2106 includes cycle-by-cycle current limiting and under voltage lockout. The internal power switches, combined with the tiny 10-pin MSOP and QFN packages, provide a solution requiring a minimum of surface area.
