3.6A, 1MHz, Synchronous, Step-Up Converter with Output Disconnect
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 P-channel 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.
The 1MHz switching frequency allows small external components while internal compensation and soft start minimize the external component count, making the MP3415 a compact solution for a wide current load range.
The MP3415 features an integrated power MOSFET that supports an output up to 5.5V and a peak switching current above 3.6A.
The MP3415 is available in a small QFN-12 (2mmx2mm) package.

3.6A Synchronous Step-Up Converter with Output Disconnect Evaluation Board
EV3415-G-00A Evaluation Board is designed to demonstrate the capability of MP3415. The MP3415 is a high-efficiency, synchronous, current-mode, step-up converter with output disconnect.
The MP3415 provides 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.
The 1MHz switching frequency allows for small external components, while the internal compensation and the soft-start minimize the external component count. The MP3415 is available in a small 12-pin QFN 2mm x 2mm package.
