DC DC Switching Controllers Procurement Notes

Verify the specific suffix '2' against the official Texas Instruments datasheet to confirm the exact pinout and functional configuration. Ensure the SOIC-14 package dimensions match the target PCB footprint. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

DC DC Switching Controllers Selection Notes

Select this controller when designing LLC resonant topologies requiring low quiescent current during light-load conditions. The wide input voltage range accommodates various bus architectures without additional pre-regulation stages. Consider the thermal performance of the SOIC-14 package relative to the expected power dissipation in the application environment.
