The MP174AGS-P from Monolithic Power Systems is a non-isolated offline regulator supporting Boost, Buck, Buck-Boost, and Flyback topologies. It integrates a 700V switch, operates with a 5.3V to 5.6V Vcc supply, and delivers up to 5 W. Open Loop, Over Load, Over Temperature, Short Circuit, and UVLO protection are included, along with soft start, in an 8-SOIC package rated -40°C to 125°C (TJ).

  • 700V integrated switch supports direct-coupled offline regulation.
  • Flexible Boost, Buck, Buck-Boost, and Flyback topology support.
  • Comprehensive protection including UVLO, Open Loop, and Short Circuit improves safety.
  • Soft start reduces start-up stress.
  • Compact 8-SOIC package and 5 W rating suit space-constrained designs.

Non-Isolated Offline Regulators

With a 700V integrated switch and non-isolated topology support, this device suits direct-coupled offline regulation for small appliances and controls.

Buck and Buck-Boost Supplies

Support for Buck and Buck-Boost topologies enables flexible step-down and step-up/down non-isolated power conversion up to 5 W.

Smart Home and IoT Power

The 5 W rating and compact 8-SOIC package make it suitable for non-isolated bias supplies in smart home and IoT devices.

Industrial Auxiliary Rails
