MP173GJ-Z Description

Short technical summary and product information.

The MP173GJ-Z from Monolithic Power Systems is a primary-side regulator offering accurate constant voltage (CV) regulation without an opto-coupler. It integrates a 700V MOSFET and supports buck, boost, buck-boost, and flyback topologies, making it suitable for low-power offline applications like home appliances and standby power.

 

This regulator operates in green-mode, reducing peak current and switching frequency at light loads for improved efficiency. It provides up to 4W of output power with a maximum DCM output current of less than 180 mA and a maximum CCM output current of less than 280 mA. The device features low no-load power consumption (<30 mW) and low VCC operating current.

 

Protection features are integrated to enhance reliability, including thermal shutdown (TSD), VCC undervoltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open-loop protection. The MP173GJ-Z is available in a compact TSOT23-5 package, suitable for surface mount applications.

 

Note: This part is not recommended for new designs.
