Features: The Future of Analog IC Technology MP15 8 Small, Energy-Efficient, Off-line Reg ulator 30mW No-Load Power Consumption DESCRIPTION MP158 is a primary-side reg ulator that provides accurate constant voltage (CV) regulation without opto-co upler. It supports Buck, BuckBoost, Boo st and Flyback topologies. It has an in tegrated 500V MOSFET to simplify the st ructure and reduce costs. These feature s make it an ideal regulator for off-li ne low power applications, such as home appliances and standby power. MP158 is a green-mode-operation regulator. Both the peak current and switching frequen cy decrease as the load decreases. This feature provides excellent efficiency at light load, thus improving the overa ll average efficiency. MP158 features v arious protections, including thermal s hutdown (TSD), VCC under-voltage lockou t (UVLO), overload protection (OLP), sh ort-circuit protection (SCP), and open loop protection. MP158 is available in small TSOT23-5 package and SOIC8 package. TYPICAL APPLICATION .

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, Buck-
Boost, 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.
MP158 features various protections, including
thermal shutdown (TSD), VCC under-voltage
lockout (UVLO), overload protection (OLP),
short-circuit protection (SCP), and open loop
protection.
MP158 is available in small TSOT23-5 package
and SOIC8 package.
