The MPQ3410 is a highly efficient, synchronous, fixed frequency, current-mode step-up converter with output to input disconnect, inrush current limiting and internal soft-start. It includes an error amplifier, ramp generator, comparator, NChannel switch and P-Channel synchronous rectified switch (which greatly improves efficiency). The output disconnect feature allows the output to be completely isolated from the input in shutdown mode.
The 550kHz switching frequency allows for smaller external components producing a compact solution for a wide range of load currents. The internal compensation and soft-start minimizes the external component count and limits the inrush current during startup. The MPQ3410 has integrated power MOSFET which can support up to 6V output and typical 1.3A switch current.
The MPQ3410 is offered in a thin SOT23-5 package.

Evaluation KitGET THIS KIT
The EVQ3410DJ-00A is a MPQ3410 evaluation board that is configured to provide a regulated 3.3V output at up to 300mA from a 1.8V input or higher. The output voltage is adjustable from VIN to 6V by changing resistors on the evaluation board.
The high 500kHz switching frequency of the MPQ3410 allows for smaller external components, producing a compact solution for a wide range of load currents. The internal compensation and soft-start features further reduce the component count. The P-Channel synchronous rectified switch improves efficiency and isolates the output from the input in a shutdown condition.
