Procurement Notes
Verify the specific suffix 'ED8G' against official onsemi documentation to confirm package type and tape/reel specifications. Ensure the component meets required AEC-Q100 standards for your target application. Cross-reference with authorized distributors to confirm availability and authenticity, as automotive parts often require strict chain-of-custody verification.
Selection Notes
Select this component when a robust, single-output synchronous buck converter is needed for automotive systems requiring 1.5A load capacity. Consider the 260 kHz switching frequency for balancing EMI performance and passive component size. Verify that the 40V maximum input voltage aligns with your vehicle's transient voltage specifications.
Part Context
Part of the CS51412 family of low-voltage synchronous buck regulators from onsemi. This series is engineered specifically for automotive power management needs, offering integrated protection features and high thermal performance suitable for under-hood and cabin electronics.
Replacement Considerations
Consult onsemi datasheets for direct pin-to-pin replacements within the CS5141x or NCV5141x families. Verify electrical compatibility and automotive qualification status before substitution.
