The EV171-S-00A Evaluation Board is designed to demonstrate the capabilities of MP171. The MP171 is a primary-side constant voltage regulator providing accurate constant voltage (CV) regulation without Opto-coupler. It supports Buck, Buck-Boost, Boost and Flyback topologies.

The EV171-S-00A Evaluation Board is designed as Buck application. EV171-S-00A typically drives 5V/50mA load from 85VAC to 265VAC, at 60/50Hz.

The EV171-S-00A has an excellent efficiency and meets 2kV IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. MP171 features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), over-load protection (OLP), short- circuit protection (SCP), and open loop protection.

EV171-S-00A is the Evaluation Board for MP171 SOIC-8 package type.
