MP171A
DESCRIPTION
The MP171A is a primary-side regulator that provides accurate constant voltage (CV) regulation without an optocoupler. It supports buck, boost, buck-boost, and flyback topologies.
The device’s integrated 700V MOSFET simplifies the structure and reduces cost. This feature optimizes the device for offline, lowpower applications such as home appliances and standby power.
The MP171A is a green-mode operation regulator. Both the peak current and switching frequency lower as the load decreases. This feature provides excellent efficiency at light load, and improves the overall efficiency.
Protection features include thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open-loop detection.
The MP171A is available in TSOT23-5 and SOIC-8 packages.
