Universal Input, Non-Isolated Off-Line Regulator Evaluation Board
The EV173-J-00A evaluation board is designed to demonstrate the capabilities of MP173. The MP173 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 EV173-J-00A evaluation board is designed as Buck application. EV173-J-00A typically drives a 3W with a 12V/250mA load from 85VAC to265VAC, at 60/50Hz.
The EV173-J-00A has an excellent efficiency and meets IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. MP173 features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), over-load protection (OLP), short- circuit protection (SCP), and open-loop protection.
MP173 is available in small TSOT23-5 package and SOIC-8 package.
