MP156 Small, Energy-Efficient, Off-line Regulator 30mW No-Load Power Consumption The Future of Analog IC Technology DESCRIPTION FEATURES Primary-side constant voltage (CV) control, MP156 is a primary-side regulator that provides supporting Buck, Buck-Boost, Boost and accurate constant voltage (CV) regulation Flyback topologies without opto-coupler, support Buck, Buck-Boost, Integrated 500V/20 MOSFET Boost and Flyback topologies. It has an <30mW no-load power consumption integrated 500V MOSFET to simplify the structure and reduce costs. These features Up to 4W output power make it a competitive candidate for off-line low Maximum DCM output current less than power applications, such as home appliances 130mA and standby power. Maximum CCM output current less than 220mA MP156 is a green-mode-operation regulator. Low VCC Operating Current Both its the peak current and the switching Frequency foldback frequency decrease as the load decreases to Limited maximum frequency provide excellent efficiency at light load, thus Peak-current compression improving the overall average efficiency. Internal high-voltage current source MP156 features various protections, including Internal 350ns leading-edge blanking thermal shutdown (TSD), VCC under-voltage Thermal shutdown (auto restart) lockout (UVLO), overload protection (OLP), VCC under voltage lockout with hysteresis short-circuit protection (SCP), and open loop Timer based over-load protection. protection. Short-circuit protection MP156 is available in the TSOT23-5 and Open-loop protection SOIC8 packages. APPLICATIONS Home appliances, white goods and consumer electronics Industrial controls Standby power All MPS parts are lead-free and adhere to the RoHS directive.
