MP1583 PDF Datsheet – Step-Down Converter

A step-down converter, also known as a buck converter, is a type of DC-DC converter used to step down or reduce the voltage level of a DC power source to a lower voltage level, which is usually required for powering various electronic devices and components. It operates by controlling the on-off switching of its components to regulate the output voltage.

Description

The MP1583 is a step -down regulator with a built-in internal Power MOSFET. It achieves 3A of continuo us output current over a wide input supply range with excellent load and line regulation. Current mo de operatio n provides f ast transien t response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting a nd thermal shutdown. An adjustab le soft-start reduces the stress on the input source at startup. In shutdown mode the regulator dr aws 20 μA of supply current. The MP158 3 requires a minimu m number of external components, providing a compact solution.
