MP150GS-Z 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 home appliances and standby power.MP150GS-Z 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 MP150GS-Z features various protections, including thermal shutdown (TSD), VCC undervoltage lockout (UVLO), over-load protection (OLP), short-circuit protection (SCP), and open loop protection.MP150GS-Z is available in the TSOT23-5 and SOIC8 packages. 9icnet Electronics is an authorized Monolithic Power Systems distributor.
