Monolithic Power Systems (MPS) MP172A Non-Isolated Offline Regulator
Monolithic Power Systems (MPS) MP172A Non-Isolated Offline Regulator 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, low-power applications such as home appliances and standby power.
Monolithic Power Systems (MPS) MP172A is a green-mode operation regulator. The peak current and switching frequency are lowered as the load decreases. This feature provides excellent efficiency at light load and improves the overall average efficiency. Protection features include thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open-loop detection.
