Hot-selling and scarce MP1472GJ-Z 2A, 18V Synchronous Rectified Step-Down Converter SOT23

Product Descriptions

The MP1472 is a monolithic synchronous buck regulator. The device integrates a 175mΩ highside MOSFET and a 115mΩ low-side MOSFET that provide 2A of continuous load current over a wide input voltage of 4.75V to 18V. Current mode control provides fast transient response and cycle-by-cycle current limit.

An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1µA.

This device, available in an 8-pin TSOT23-8 package, provides a very compact solution with minimal external components.
