About This Product

■Summary

The MP173A is a primary-side regulator that provides accurate constant voltage (CV) regulation without an optocoupler. Supports buck, boost, buck-boost, and flyback topologies. A 700V MOSFET integrated into the device simplifies the structure and reduces cost. This feature optimizes the device for offline, low-power applications such as consumer electronics and standby power. MP173A is a green mode operating regulator. As the load decreases, both the peak current and switching frequency decrease. This feature provides superior efficiency at light loads and increases overall efficiency. Protection features include thermal shutdown (TSD), undervoltage lockout (UVLO) on VCC, overload protection (OLP), short-circuit protection (SCP), and open-loop detection. MP173A is offered in TSOT23-5 and SOIC-8 packages.

■Features and benefits

・Primary side CV control - Supports buck, buck-boost, boost and flyback topologies ・Integrated 700V MOSFET and current source ・No-load power consumption less than 30mW ・Output power up to 4W ・Maximum DCM output current less than 180mA ・Maximum CCM output current less than 280mA ・Low VCC operating current ・Frequency foldback ・Maximum frequency limit ・Peak current compression ・Internal bias VCC ・TSD, UVLO, OLP, SCP, open loop detection ・Available in TSOT23-5 and SOIC-8 packages

■Available product numbers

・MP173AGJ-P MP173AGJ-Z MP173AGS-P MP173AGS-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
