MP158 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, MP158 is a primary-side regulator that provides supporting Buck, Buck-Boost, Boost and accurate constant voltage (CV) regulation Flyback topologies without opto-coupler. It supports Buck, Buck- Integrated 500V MOSFET and current Boost, Boost and Flyback topologies. It has an source integrated 500V MOSFET to simplify the <30mW no-load power consumption structure and reduce costs. These features make it an ideal regulator for off-line low power Up to 2W output power applications, such as home appliances and Maximum DCM output current less than standby power. 40mA Maximum CCM output current less than MP158 is a green-mode-operation regulator. 70mA Both the peak current and switching frequency Low VCC Operating Current decrease as the load decreases. This feature Frequency foldback provides excellent efficiency at light load, thus Limited maximum frequency improving the overall average efficiency. Peak-current compression MP158 features various protections, including Internally biased VCC 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 MP158 is available in small TSOT23-5 package Open-loop protection and SOIC8 package.
