MP1570DN-LF-Z

The MP1570 is a monolithic synchronous buck regulator. The device integrates 100m? MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.75V to 23V. 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 output is actively discharged by transferring energy in the output capacitor to the input capacitor, dropping the supply current to 1µA. This device, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components.
