MP3414E

1.8A, 1MHz, High-Efficiency, Synchronous Step-Up Converter with Output Disconnect

Datasheet

Description

The MP3414E is a high-efficiency, current-mode, synchronous step-up converter with output disconnect. It can start up from an input voltage (V_IN) as low as 0.8V. The device provides inrush current limiting and output short-circuit protection (SCP).

The integrated, P-channel synchronous rectifier improves efficiency and eliminates the requirement of an external Schottky diode. If the part shuts down, then the P-channel MOSFET disconnects the output from the input. Output disconnect allows the output to be discharged completely, which allows for the 1μA supply current in shutdown mode (I_SD).

The fixed 1MHz switching frequency (f_SW) allows for smaller external components. Internal compensation and soft start (SS) reduce the external component count, providing a compact solution. The MP3414E features an integrated power MOSFET that supports up to 4V of output voltage (V_OUT) and up to 1.8A of peak current (I_PEAK).

The MP3414E is available in a small TSOT23-8 package.
