MP171AGS Datasheet Primary-side Regulator

Manufacturer: Monolithic Power Systems

Overview: MP171A 700V, Non-Isolated, Offline Regulator, Up to 60mA Output Current with Improved EMI.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MP171A is a primary-side regulator that provides accurate constant voltage (CV) regulation without an optocoupler.

It supports buck, boost, buck-boost, and flyback topologies.

The device’s integrated 700V MOSFET simplifies the structure and reduces cost.

Key Features

  • include thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open-loop detection. The MP171A is available in TSOT23-5 and SOIC-8 packages.
