EV173A-S-00A Universal Input, Non-Isolated Off-Line Regulator With Improved EMI Performance Evaluation Board DESCRIPTION FEATURES The EV173A-S-00A Evaluation Board is Primary-Side non-isolated Constant Voltage designed to demonstrate the capabilities of (CV) Control MP173A. The MP173A is a primary-side < 30mW No-load power consumption constant voltage regulator, which provides Up to 3W output power accurate constant voltage (CV) regulation Good EMI Performance without Opto-coupler. It supports Buck, Limited Maximum Frequency Buck-Boost, Boost and Flyback topologies. Multiple Protections: SCP, OCP, OTP, OLD and VCC UVLO The EV173A-S-00A Evaluation Board is Low Cost and Simple External circuit designed as Buck application. EV173A-S-00A typically outputs 3W with a 12V/250mA load APPLICATIONS from 85VAC to 265VAC input. Home Appliance, white goods and The EV173A-S-00A has excellent efficiency and consumer electronics meets IEC61000-4-5 surge immunity and Industrial Controls EN55022 conducted EMI requirements. Most of Standby Power all, the radiation performance gets improved compared with MP173. MP173A features All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For MPS green status, please visit MPS website under Quality various protections, including thermal shutdown Assurance. MPS and The Future of Analog IC Technology are Registered Trademarks of Monolithic Power Systems, Inc. (TSD), VCC under-voltage lockout (UVLO), Warning: Although this board is designed to satisfy safety over-load protection (OLP), short- circuit requirements, the engineering prototype has not been agency approved. Therefore, all testing should be performed protection (SCP), and open loop protection. using an isolation transformer to provide the AC input to the prototype board. MP173AGS is available in SOIC8 package.
