The MPQ3413 is a high-efficiency, synchronous, current mode step-up converter with output disconnect. The MPQ3413 can start up from an input voltage (V_IN) as low as 2.8V, and provides inrush current limiting and output short-circuit protection (SCP).

The integrated P-channel synchronous rectifier (SR) improves efficiency and eliminates the requirement of an external Schottky diode. The MPQ3413’s P-channel MOSFET disconnects the output from the input when the MPQ3413 shuts down. The output disconnect feature allows the output to be discharged completely, allowing the MPQ3413 to draw a supply current below 1μA in shutdown mode.

The 2.2MHz switching frequency (f_SW) allows for smaller external components, while internal compensation and soft start (SS) minimize the external component count. These features result in a compact solution across a wide current load range.

The MPQ3413 features an integrated power MOSFET that supports a 5V output voltage (V_OUT) and a peak switching current above 1.5A.

The MPQ3413 is available in a small TSOT23-8 package.
