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.

Parametrics

Offline Primary Side 6W Regulator
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. A 500V MOSFET is integrated in the regulator, so very simple structure and low cost can be achieved. These features make MP157 an ideal solution for off-line low power applications. Typical applications include home appliance, standby power and industrial control. MP157 is a green mode operation regulator. When the load decreases, the peak current and the switching frequency decrease with the load. As a result, it still offers excellent efficiency performance at light load, thus better average efficiency is achieved. MP157 features various protections like Thermal Shutdown (TSD), VCC under Voltage Lockout (UVLO), Over Load Protection (OLP), Short Circuit Protection (SCP), Open Loop Protection. MP157 is available in the TSOT23-5 and SOIC8 packages.
