MP163BGS-33-Z

AC DC Converters, Offline Switchers Overview

The MP163BGS-33-Z is a non-isolated offline switching regulator from Monolithic Power Systems, designed for applications requiring up to 3W of output power. It integrates a 3.3V LDO and supports Buck, Boost, Flyback, and Buck-Boost topologies. The device operates with an input voltage range of 5.1V to 5.8V and delivers an output current of 420mA. It features a shutdown function and operates within a temperature range of -40°C to +125°C. Packaged in a 16-SOIC format, it includes internal protection mechanisms.

AC DC Converters, Offline Switchers Feature Summary

• Integrates a 3.3V output Low Dropout Regulator (LDO) alongside the main switching controller.
• Supports multiple converter topologies including Buck, Boost, Flyback, and Buck-Boost configurations.
• Includes comprehensive fault protection features such as overcurrent, overtemperature, and UVLO.

AC DC Converters, Offline Switchers Applications

• Non-isolated offline power supply designs
• Low-power consumer electronics requiring integrated regulation
• Industrial control systems operating within specified voltage ranges

AC DC Converters, Offline Switchers Procurement Notes

Verify the exact suffix 'Z' against official MPS documentation to confirm packaging and compliance specifications. Ensure the design accommodates the specific 5.1V to 5.8V input window and 420mA output capability. Confirm thermal management requirements for the SOIC-16 package under maximum load conditions at elevated temperatures.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a non-isolated offline solution with an integrated LDO is required for low-power applications. Compare the 420mA output current against system demands to ensure adequate headroom. Evaluate the 16-SOIC footprint against available PCB space and verify compatibility with the supported Buck, Boost, and Flyback topologies.

AC DC Converters, Offline Switchers Part Context

This part belongs to the MP163 series of offline regulators manufactured by Monolithic Power Systems. It shares architectural similarities with variants like the MP163AGSE-33 and MP163CGSE-33, differing primarily in specific electrical ratings and packaging options. The series targets compact, cost-effective power solutions for non-isolated applications.

AC DC Converters, Offline Switchers Replacement Considerations

MP163BGSE-33-Z is a verified direct substitute with identical specifications. MP163AGSE-33 offers similar functionality but with a lower output current rating of 210mA. Verify pinout compatibility and thermal performance when considering these alternatives.
