MP174AGJ-Z

AC DC Converters, Offline Switchers Overview

The MP174AGJ-Z is a 700V non-isolated off-line regulator from Monolithic Power Systems, designed for AC-DC conversion with up to 400mA output current. It supports Buck, Buck-Boost, Boost, and Flyback topologies within a TSOT-23-5 package. The device operates at a Vcc of 5.3V to 5.6V, features an internal switch, and includes soft-start control. It provides comprehensive fault protection against open circuits, overloads, overtemperature, and short circuits, functioning reliably between -40°C and +125°C.

AC DC Converters, Offline Switchers Feature Summary

• Integrated high-voltage 700V switch enabling direct connection to off-line power sources without external isolation transformers.
• Multi-topology flexibility supporting Buck, Buck-Boost, Boost, and Flyback configurations for diverse voltage regulation needs.
• Enhanced EMI performance characteristics to assist in meeting electromagnetic interference standards.
• Built-in protection mechanisms including soft-start, overcurrent, overvoltage, and thermal shutdown safeguards.

AC DC Converters, Offline Switchers Applications

• Non-isolated AC-DC power supplies
• Offline LED drivers
• Low-power adapter designs

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'GJ' corresponds to the TSOT-23-5 package variant when sourcing. Confirm RoHS compliance status as indicated by the '-Z' designation. Ensure design compatibility with the specified 5.3V to 5.6V Vcc operating range. Check for obsolescence notices as some distributors list this part as not recommended for new designs.

AC DC Converters, Offline Switchers Selection Notes

Select this component for applications requiring a compact solution for low-current off-line regulation. The integrated 700V switch eliminates the need for external high-voltage MOSFETs. Consider the TSOT-23-5 footprint constraints during PCB layout. Evaluate thermal management requirements given the small package size and potential power dissipation in enclosed spaces.

AC DC Converters, Offline Switchers Part Context

This regulator belongs to the MP174A series from Monolithic Power Systems, which focuses on efficient offline power conversion. The series offers various package options, including SOIC-8 variants like the MP174AGS-Z, providing designers with flexibility in thermal and spatial requirements while maintaining similar electrical performance characteristics.

AC DC Converters, Offline Switchers Replacement Considerations

The MP174AGS-Z serves as a pin-compatible alternative offering the same electrical specifications but housed in an SOIC-8 package for improved thermal handling. Designers must verify footprint compatibility when substituting between these package types.
