It is qualified to AEC-Q100, making it suitable for automotive power supplies — under-hood ECUs, infotainment rails, or sensor bias generators — where the supply voltage can swing from 1.8 V to 28 V. The controller drives an external N-channel MOSFET and operates with a single output phase. ## Key ratings and what they mean for your BOM The switching frequency range of 100 kHz to 500 kHz lets you trade off inductor size against switching losses. The 90% maximum duty cycle supports moderate step-up ratios in boost or SEPIC. ## Lifecycle and sourcing reality The MAX669EUB/V+ is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window has been announced. For a BOM line that needs automotive-grade qualification, this part is a stable choice — no imminent obsolescence risk. Sourcing is through independent distribution; current pricing and lead time are confirmed at quote time against an RFQ.","metaTitle":"MAX669EUB/V+ Switching Controller, AEC-Q100, 100kHz–500kHz","metaDescription":"MAX669EUB/V+ automotive-qualified switching controller from Maxim Integrated.
