Procurement Notes
Verify the specific suffix 'M6X' against the manufacturer's official datasheet to confirm packaging details and pinout compatibility. Ensure the selected variant matches the required linear dimming characteristic, as distinct from other series options. Cross-reference the ordering number with the latest onsemi documentation to validate RoHS compliance and material declarations before finalizing procurement.
Selection Notes
Select this component for designs requiring a compact SOT-23-6 footprint with wide input voltage tolerance. It is suitable for applications needing simultaneous analog and PWM dimming control with a linear response profile. Consider the 1 MHz switching frequency for inductor size optimization and verify thermal performance within the specified operating temperature range.
