Product Description

The EV175-S-00AEvaluation Board is designed to demonstrate the performance of MP175. The MP175 is a high performance and cost effective primary-side constant voltage regulator, which is ideal for home appliances, standby power and etc.

The EV175-S-00A is configured as a buck topology. It delivers 18V/550mA output.

The EV175-S-00A has an excellent efficiency and meets 1kV IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. It has multi-protection function: such as open circuit protection, over load protection, short-circuit protection and over-temperature protection, etc.

Product Features

  • Primary-Side non-isolated Constant Voltage Control (CV)
  • Integrated 700V MOSFET with Minimal External Components
  • Peak-Current Control with Peak Current Compression
  • Limited Maximum Frequency and Frequency Foldback
  • Multiple Protections: SCP, OLP, OTP, open loop and VCC UVLO
  • Low Cost and Simple External circuit


700V, Non-Isolated, Offline Regulator, Up to 600mA Output Current

The MP175 is a primary-side regulator that provides accurate, constant voltage (CV) regulation without an optocoupler. The MP175 supports buck, buck-boost, boost, and flyback topologies. The MP175 has an integrated 700V MOSFET and high-voltage current source, and also has a fixed output option to further simplify the structure and reduce costs. The output voltage can also be adjusted for various applications.

The MP175 is a green-mode-operation regulator. Both the peak current limit and switching frequency decrease with decreasing load. This feature provides excellent efficiency at light-load condition and improves the overall average efficiency.

The MP175 has multiple protections features, including over-temperature protection (OTP), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), brown-out protection (BOP), and open-loop detection (OLD).

These features make the MP175 an ideal regulator for offline, low-power applications, such as home appliances and standby power.

The MP175 is available in a SOIC-8 package.
