Learn about our Evaluation Kit
Product Description
The EV158-S-00A Evaluation Board is designed to demonstrate the capabilities of MP158. The MP158 is a primary-side constant voltage regulator providing accurate constant voltage (CV) regulation without Opto-coupler. It supports Buck, Buck-Boost, Boost and Flyback topologies.
The EV158-S-00A Evaluation Board is designed as Buck application. EV158-S-00A typically drives 5V/50mA load from 85VAC to 265VAC, at 60/50Hz.
The EV158-S-00A has an excellent efficiency and meets 1kV IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. MP158 features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), over-load protection (OLP), short- circuit protection (SCP), and open loop protection.

Parametrics
Small Energy Efficient Offline Regulator for low Wattage
MP158 is a primary-side regulator that provides accurate constant voltage (CV) regulation without opto-coupler. It supports Buck, Buck-Boost, Boost and Flyback topologies. It has an integrated 500V MOSFET to simplify the structure and reduce costs. These features make it an ideal regulator for off-line low power applications, such as home appliances and standby power. MP158 is a green-mode operation regulator. Both the peak current and switching frequency decrease as the load decreases. This feature provides excellent efficiency at light load, thus improving the overall average efficiency. MP158 features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open loop protection. MP158 is available in small TSOT23-5 package and SOIC8 package.
