The MP163 is a primary-side regulator that provides accurate, dual-output, constant voltage (CV) regulation without an optocoupler. The MP163 supports buck, boost, buck-boost, and flyback topologies and has an integrated 700V MOSFET and an LDO to simplify the structure and reduce cost. These features make the MP163 an ideal regulator for offline, low-power applications, such as home appliances and standby power. The MP163 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 and improves overall average efficiency. Full protection features include thermal shutdown, VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open-loop protection.The MP163 is available in SOIC16 and SOIC8-7B packages.
