Procurement Notes

Verify the exact part number against official manufacturer documentation to ensure compatibility with specific design requirements. Confirm that the USP-10 package dimensions align with your PCB layout constraints. Check for any specific ordering suffixes or revisions that may affect electrical characteristics or pinout configurations before finalizing procurement decisions.

Selection Notes

Select this component when a dual-channel solution combining buck and inverting functions is required in a small footprint. Consider the 180 kHz switching frequency and 20 mA output capability relative to load demands. Ensure the operating temperature range meets environmental specifications and that the input voltage range supports the intended application's power source.
