MP150 is a primary-side regulator that provides accurate constant voltage (CV) regulation without the opto-coupler, and supports buck, buck-boost and flyback topologies. It has an integrated 500V MOSFET that simplifies the structure and reduces costs. These features help to make it a competitive candidate for off-line low power applications, such as home appliances and standby power. MP150 is a green-mode operation regulator. Both the peak current and switching frequency decrease as the load decreases to provide excellent efficiency performance at light load, thus improving the overall average efficiency. The MP150 features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), over-load protection (OLP), short-circuit protection (SCP), and open loop protection. MP150 is available in the TSOT23-5 and SOIC8 packages.

MP150 is a primary side regulator providing accurate constant voltage (CV) regulation without the Opto-coupler, support Buck, Buck-Boost and Flyback topologies. 500V MOSFET is integrated in the regulator, so very simple structure and low cost can be achieved. These features help to make it a competitive candidate for off-line low power applications, such as home appliance and standby power.
MP150 is a green mode operation regulator. With the load decreasing, the peak current and the switching frequency will both decreasing with the load. As a result, it still offers excellent efficiency performance at light load, thus better average efficiency is achieved.
MP150 features various protections like Thermal Shutdown (TSD), VCC under Voltage Lockout (UVLO), Over Load Protection (OLP), Short Circuit Protection (SCP), Open Loop Protection.
