MP163CGS-33-P

AC DC Converters, Offline Switchers Overview

The MP163CGS-33-P is a primary-side constant voltage (CV) regulator from Monolithic Power Systems, designed for offline low-power applications. It supports Buck, Boost, Buck-Boost, and Flyback topologies without requiring an optocoupler. The device integrates a 700V MOSFET and an internal LDO optimized for dual-output configurations. Key electrical parameters include a 3.3V output voltage, up to 4W of output power, and less than 30mW no-load power consumption. It operates within a temperature range of -40°C to +125°C and features frequency foldback and peak-current compression for enhanced efficiency.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'GS' against the requested 'GSE' variant, as package or pinout differences may exist between SOIC-16 revisions. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements for your assembly process. Check for active part availability versus end-of-life notifications, as distribution channels may vary. Ensure the 700V rating aligns with your system's voltage stress requirements.

AC DC Converters, Offline Switchers Selection Notes

Select this component when designing non-isolated offline converters requiring high integration and cost reduction. The integrated 700V MOSFET removes external switching components, while the internal LDO simplifies auxiliary power generation. Ideal for designs prioritizing light-load efficiency through green-mode operation. Suitable for space-constrained applications due to the compact SOIC-16 packaging and reduced external component count.
