The EV174A-S-00A Evaluation Board is designed to demonstrate the capabilities of MP174A. The MP174A is a primary-side constant voltage regulator, which provides accurate constant voltage (CV) regulation without Opto-coupler. It supports Buck, Buck-Boost, Boost and Flyback topologies.

The EV174A-S-00A Evaluation Board is designed as Buck application. EV174A-S-00A typically outputs 3.6W with a 12V/300mA load from 85VAC to 265VAC input.

The EV174A-S-00A has excellent efficiency and meets IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. Most of all, the radiation performance gets improved compared with MP174. MP174A features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), over-load protection (OLP), short-circuit protection (SCP), and open loop protection.

MP174AGS is available in SOIC8 package.
