AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix Z indicates RoHS compliance status through official manufacturer documentation. Confirm the SOIC-8 package dimensions against ECAD models before integration. Ensure the 5.5 V to 5.7 V input voltage range aligns with your system's supply characteristics. Check humidity sensitivity handling requirements during storage and assembly processes.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a non-isolated offline regulator with improved EMI performance is required. The MP173AGS-Z is suitable for applications needing Buck, Buck-Boost, or Flyback configurations. Consider the 280 mA output current limit and the 5.5 V to 5.7 V input range. The SOIC-8 package offers SMD/SMT mounting options. Evaluate the -40 C to +125 C operating temperature range for environmental suitability.

AC DC Converters, Offline Switchers Part Context

The MP173AGS-Z belongs to the MP173A series of power management ICs from Monolithic Power Systems. It is categorized under switching voltage regulators and PMIC products. The series focuses on non-isolated offline regulation with enhanced electromagnetic interference characteristics. This part is distinct from the MP174A series which offers higher output current capabilities.

AC DC Converters, Offline Switchers Replacement Considerations

The MP173AGJ-Z is a verified substitute offering identical electrical specifications but housed in a TSOT-23-5 package instead of SOIC-8. Both parts share the same 280 mA output current and input voltage range.
