Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and variant selection. Confirm that the requested part number matches the exact electrical specifications required for the target application, as minor suffix variations may indicate differences in tape-and-reel configurations or thermal ratings. Cross-reference the datasheet revision date to ensure compliance with current design standards.

Selection Notes

Select this component when a compact solution with a fixed 5.5 V output is required for driving high-power LEDs from a single-cell lithium-ion battery source. The 2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the input voltage range aligns with the available power supply rails and that the 700 mA flash current capability meets the peak illumination requirements of the design.
