MP3414 Datasheet | Monolithic Power Systems

DESCRIPTION The MP3414 is a high-efficiency, synchronous, current- mode, step-up converter with output disconnect. The MP3414 can start up from an input voltage as low as 0.8V to provide inrush current limiting, and output short-circuit protection. The integrated, P-channel, synchronous rectifier improves efficiency and eliminates the need for an external Schottky diode. The PMOS disconnects the output from the input when the part shuts down. This output disconnect feature allows the output to be pletely discharged, thus allowing the part to draw a 1μA supply current in shutdown mode. The 1MHz switching frequency allows for smaller external ponents, while the internal pensation and the soft-start minimize the external ponent count: these feature help to produce a pact solution for a wide current load range. The MP3414 features an integrated power MOSFET that supports up to a 4V output and a typical 1.8A peak switching current. The MP3414 is available in a small 8-pin TSOT23 package.
