MP171 700V Non-Isolated Regulator up to 60mA Output Current

Product Detail

MP171 is a primary-side regulator that provides accurate constant voltage (CV) regulation without an opto-coupler. It supports buck, boost, buck-boost, and flyback topologies. It has an integrated 700 V MOSFET to simplify the structure and reduce cost. These features make it an ideal regulator for offline low-power applications, such as home appliances and standby power. MP171 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 the overall average efficiency. MP171 has various protection features including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open-loop protection. MP171 is available in a small TSOT23-5 package and SOIC-8 package.
