MP3418
DESCRIPTION
The MP3418 is a high-efficiency, synchronous, current- mode, step-up converter with output disconnect. The MP3418 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 less than 1µA in shutdown mode. The 1.2MHz 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 MP3418 is available in a small 8-pin TSOT23 package.
