The Future of Analog IC Technology MP158 Small, Energy-Efficient, Off-line Regulator 30mW No-Load Power Consumption DESCRIPTION MP158 is a primary-side regulator that provides accurate constant voltage (CV) regulation without opto-coupler. It supports Buck, BuckBoost, Boost and Flyback topologies. It has an integrated 500V MOSFET to simplify the structure and reduce costs. These features make it an ideal regulator for off-line low power applications, such as home appliances and standby power. MP158 is a green-mode-operation regulator. Both the peak current and switching frequency decrease as the load decreases. This feature provides excellent efficiency at light load, thus improving the overall average efficiency.
