MP155GJ-Z Monolithic Power Systems

MP155 Energy Efficient Off-line Regulator The Future of Analog IC Technology DESCRIPTION FEATURES Primary-side constant voltage (CV) control, The MP155 is a primary-side regulator that supporting Buck, Buck-boost, Boost and provides accurate constant voltage regulation Flyback topologies without the opto-coupler, and supports Buck, Integrated 500V/20 MOSFET Buck-boost, Boost and Flyback topologies. An < 100mW No-load power consumption integrated 500V MOSFET simplifies the structure and reduces costs. These features Up to 4W output power make it a competitive candidate for off-line low- Maximum DCM output current of 130mA power applications, such as home appliances Maximum CCM output current of 220mA and standby power. Low VCC operating current Frequency foldback The MP155 is a green-mode-operation Maximum frequency limit regulator. Both the peak current and the Peak current compression switching frequency decrease as the load Internal high-voltage current source decreases. As a result, it offers excellent efficiency performance at light load, thus Internal 350ns leading-edge blanking improving the overall average efficiency. Thermal shutdown (auto restart) VCC under-voltage lockout with hysteresis The MP155 features various protections such (UVLO) as thermal shutdown (TSD), VCC under-voltage Timer-based overload protection. lockout (UVLO), overload protection (OLP), Short circuit protection short-circuit protection (SCP), and open loop Open loop protection protection. The MP155 is available in the TSOT23-5 and APPLICATIONS SOIC8 packages. Home Appliances, white goods and consumer electronics Industrial Controls Standby Power All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
