The MPQ3413 is a high-efficiency, synchronous, current mode step-up converter with output disconnect. The MPQ3413 can start up from an input voltage (VIN) 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 (fSW) 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 (VOUT) and a peak switching current above 1.5A.
The MPQ3413 is available in a small TSOT23-8 package.
