The EV174-S-00A Evaluation Board is designed to demonstrate the capabilities of MP174. The MP174 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 EV174-S-00A Evaluation Board is designed as Buck application. EV174-S-00A typically drives a 3.6W with a 12V/300mA load from 85VAC to 265VAC, at 60/50Hz.
The EV174-S-00A has an excellent efficiency and meets IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. MP174 features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), over-load protection (OLP), short- circuit protection (SCP), and open loop protection.
