The Future of Analog IC Technology
DESCRIPTION
The MP3415 is a high-efficiency, synchronous, current-mode, step-up converter with output disconnect.
The MP3415 can start up with an input voltage as low as 1.8V while providing inrush current limiting and output short-circuit protection (SCP). The integrated, P-channel, synchronous rectifier improves efficiency and eliminates the need for an external Schottky diode. The Pchannel MOSFET disconnects the output from the input when the MP3415 shuts down. Output disconnect discharges the output completely, allowing the MP3415 to draw a supply current below 1μA in shutdown mode.
