EV157-J-00A
Active
Smallest Energy Off-line Regulator, EV Board
Product Description
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.
MP157GJ is available in the TSOT23-5 packages.
