2018 MPS. All Rights Reserved. DESCRIPTION The EV020-5-S-00C Evaluation Board is designed to demonstrate the capabilities of MP020-5. The MP020-5 is a primary-side-control regulator which can eliminates secondary feedback components. The EV020-5-S-00C is typically designed for small appliances which output 12V/0.3A and 5V/0.1A load from 85VAC to 265VAC, 50HZ/60HZ. The EV020-5-S-00C has an excellent efficiency and meets IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. It has multi-protection function as open circuit protection, short-circuit protection, cycle by cycle current limit and over-temperature protection, etc. ELECTRICAL SPECIFICATION Parameter Symbol Value Units Input Voltage VIN
