The MAX16990ATCD/VY+T is a current-mode PWM controller from Analog Devices designed for boost and SEPIC topologies in automotive systems. It is part of the Automotive, AEC-Q100 series, qualified for under-hood and cabin electronics where reliability over -40°C to +125°C junction temperature is required. The controller drives a single external N-channel MOSFET with a maximum duty cycle of 93%, switching from 220kHz up to 1MHz. Supply voltage range of 4.5V to 36V covers cold-crank and load-dump conditions common in 12V and 24V vehicle electrical systems. ## Key features for the BOM decision Clock sync input allows the switching frequency to be locked to an external clock, useful for avoiding beat frequencies in multi-rail power stages or sensitive RF sections. Control features include current limit, enable, frequency control, and power good. No synchronous rectifier means the controller uses an external diode — simpler but slightly lower efficiency than a sync-rectified design. The 12-TQFN-SW (3x3) package with wettable flank supports automated optical inspection (AOI) in production, a plus for automotive assembly lines. ## Where it fits in the system Typical applications include automotive LED lighting, infotainment supply rails, and sensor bias generators where a boosted or SEPIC-regulated voltage is needed from a battery bus. The 4.5V minimum supply lets it operate through engine start dips. The 125°C junction rating is sufficient for under-hood placement, though thermal pad layout and PCB copper area must be sized for the dissipation — the exposed pad is the primary heat path.","metaTitle":"MAX16990ATCD/VY+T Automotive Boost/SEPIC Controller","metaDescription":"MAX16990ATCD/VY+T is an automotive-grade boost/SEPIC controller from Analog Devices.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up, Step-Up/Step-Down","Topology":"Boost, SEPIC","Clock Sync":"Yes","Output Type":"Transistor Driver","Mounting Type":"Surface Mount, Wettable Flank","Output Phases":"1","Package / Case":"12-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Current Limit, Enable, Frequency Control, Power Good","Duty Cycle (Max)":"93%","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"220kHz ~ 1MHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Supplier Device Package":"12-TQFN-SW (3x3)","Voltage - Supply (Vcc/Vdd)":"4.5V ~ 36V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.33","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.33000","currency":"USD"},{"qty":10,"price":"$4.78400","currency":"USD"},{"qty":25,"price":"$4.52240","currency":"USD"},{"qty":100,"price":"$3.91930","currency":"USD"},{"qty":250,"price":"$3.71832","currency":"USD"},{"qty":500,"price":"$3.33644","currency":"USD"},{"qty":1000,"price":"$2.81386","currency":"USD"},{"qty":2500,"price":"$2.67317","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/55d7480df3dcf4d21ee3915f40d5a37b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can the MAX16990 be used for automotive LED lighting?","answer":"Yes.
