Monolithic Power Systems MP150

Description

MP150 is a primary-side regulator that provides accurate constant voltage (CV) regulation without the opto-coupler, and supports Buck, Buck-boost, 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 offline low power applications, such as homeappliances 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 undervoltage lockout (UVLO), over-load protection (OLP), short-circuit protection (SCP), and open loop protection.

MP150 is available in the TSOT23-5 and SOIC8 packages.
