• High-voltage LED string driving applications

LED Driver IC Procurement Notes

Verify the specific suffix 'V+' against the official Analog Devices datasheet to confirm pinout and thermal pad configuration. Ensure the selected variant matches the required automotive qualification standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the SWTQFN-EP-24 package footprint aligns with the PCB design constraints.

LED Driver IC Selection Notes

Select this component when designing automotive displays requiring four independent backlight channels with high voltage headroom. The integrated boost controller simplifies bill of materials by eliminating external power stages. Consider the 2.2MHz switching frequency for EMI management and component size optimization. Verify that the 130mA per channel output meets the total luminance requirements of the target display panel.
