2A, 6V, 740KHz Synchronous Buck Converter



The MP2108 is a 2A, 740kHz 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 740KHz switching frequency allows for small filtering components, further reducing the solution size. The MP2108 includes cycle-by-cycle current limiting and under voltage lockout. Internal power switches, combined with the tiny 10-pin MSOP or 3mm x 3mm QFN packages, provide a solution requiring a minimum of board space. QFN package is recommended if output current is higher than 1.5A.
