Product Description

The EV157-S-00A Evaluation Board is designed to demonstrate the capabilities of MP157GS. 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-S-00A Evaluation Board is designed as Buck application. The EV157-S-00A typically drives a 4.2W with a 12VTYP, 350mA load from 85VAC to 265VAC, at 50Hz.

The EV157-S-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.

MP157GS is available in the SOIC8 packages.
