All Rights Reserved. 1 EV150-J -00A –OFFLINE P RIMARY S IDE REGULATOR DESCRIPTION MP150 is a primary side regulator providing accurate constant voltage (CV) regulation without the Opto-coupler, support Buck, BuckBoost 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. FEATURES • • • • • • • • • Primary side constant voltage (CV) control, supporting Buck, Buck-Boost and Flyback topologies Integrated 500V/30Ω MOSFET < 150mW No-load power consumption Up to 1W output power Maximum DCM output current lower than 120mA, maximum CCM output current lower than 200mA Frequency Foldback Maximum frequency limitation Peak Current Compression Internal High Voltage Current Source All MPS parts are lead-free and adhere to the RoHS directive.
