AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'G4' if lead-free compliance or specific manufacturing lot requirements are mandatory for your assembly process. Confirm that the SOIC-16 surface mount package aligns with your PCB footprint design rules. Ensure the 1 MHz switching frequency capability matches your electromagnetic interference constraints and passive component ratings.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a single-output high-speed PWM controller is required for isolated or non-isolated topologies. Consider the 2 A peak output drive capability for direct gate driving applications without external buffers. Evaluate the 100% duty cycle limit against your specific application's continuous conduction requirements compared to models with lower maximum duty cycles.

AC DC Converters, Offline Switchers Part Context

This part belongs to the UC3823 family of switching controllers from Texas Instruments. It shares functional similarities with the UC3823N and UC3823DW variants but differs in packaging and thermal characteristics. The BDWTR designation indicates a specific temperature grade and tape-and-reel packaging format suitable for automated surface-mount assembly lines.
