MP163BGSE-33-Z

AC DC Converters, Offline Switchers Overview

The MP163BGSE-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 high-voltage startup circuit and an LDO to provide a stable 3.3V auxiliary output with a maximum current of 420 mA. The device supports Buck, Boost, Flyback, and Buck-Boost topologies, operating within an input voltage range of 5.1 V to 5.8 V. It features a shutdown function, operates at temperatures between -40°C and +125°C, and utilizes a 16-SOIC surface-mount package.

AC DC Converters, Offline Switchers Feature Summary

• Integrates a dedicated 3.3V output LDO for auxiliary power generation
• Supports multiple converter topologies including Buck, Boost, and Flyback
• Includes internal protection mechanisms against overcurrent and thermal stress

AC DC Converters, Offline Switchers Applications

• Offline power supplies for consumer electronics
• Auxiliary power generation in non-isolated converters
• Low-power AC/DC adapter designs

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'Z' corresponds to RoHS compliance and lead-free status as per manufacturer standards. Confirm that the SOIC-16 package dimensions align with PCB footprint requirements. Ensure the 3.3V LDO output current capability meets the load demands of the target application without exceeding the 420 mA limit.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a compact, non-isolated solution is required for low-power offline applications. The integrated LDO simplifies design by providing a clean auxiliary rail. Consider the 700V breakdown rating for high-voltage isolation barriers. Evaluate thermal performance given the 125°C maximum junction temperature constraint in enclosed environments.

AC DC Converters, Offline Switchers Part Context

This part belongs to the MP163 series of offline regulators. It shares architectural similarities with variants like the MP163AGSE-33, which offers lower output current capabilities. The 'BGSE' designation indicates specific packaging and pinout configurations within the MPS portfolio, distinguishing it from other series members with different thermal or electrical characteristics.
