DESCRIPTION
FEATURES
The EV157-J-00A Evaluation Board is designed
to demonstrate the capabilities of MP157GJ.
MP157 is a primary side regulator providing
accurate constant voltage (CV) regulation
without the Opto-coupler. It supports Buck,
Buck-Boost, Boost and Flyback topologies.
•

•
•
•
The EV157-J-00A Evaluation Board is designed
as Buck application. The EV157-J-00A typically
drives a 4.2W with a 12VTYP , 350mA load from
85VAC to 265VAC, at 50Hz.
The EV157-J-00A has excellent efficiency and
meets EN55022conducted EMI requirements. It
has multiple protections, including open-circuit
protection, short-circuit protection, over load
protection and over-temperature protection, etc.
