Product Descriptions

The MP28315 is a monolithic synchronous buck regulator. The device integrates 100mΩ MOSFETS that provide 3A continuous load current over a wide operating input voltage of 5V to 16V. Current mode control provides fast transient response and cycle-by-cycle current limit.

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

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