It delivers two fixed output voltages — 3.3 V on one channel and 1.8 V on the other — each rated for 500 mA continuous output current. The part operates from a 3.5 V to 17 V input bus. ## Switching frequency and external component sizing The 3.2 MHz switching frequency is fixed; there is no SYNC pin for external clock synchronisation. The part does not include internal synchronous rectification — an external Schottky diode per channel is required in the BOM. ## Lifecycle and compliance The MAX20019ATBA/V+T is listed as Active in production and ROHS3 compliant. For BOM planning, this part is currently available through independent distribution channels and is quoted to order against an RFQ.","metaTitle":"MAX20019ATBA/V+T Automotive Buck Regulator, Dual 500mA","metaDescription":"Maxim MAX20019ATBA/V+T automotive-grade dual step-down buck regulator.","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-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"500mA, 500mA","Number of Outputs":"2","Output Configuration":"Positive","Frequency - Switching":"3.2MHz","Operating Temperature":"-40°C ~ 125°C","Synchronous Rectifier":"No","Voltage - Input (Max)":"17V","Voltage - Input (Min)":"3.5V","Supplier Device Package":"10-TDFN-EP (2x3)","Voltage - Output (Min/Fixed)":"3.3V, 1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.20000","currency":"USD"},{"qty":10,"price":"$3.77400","currency":"USD"},{"qty":25,"price":"$3.56800","currency":"USD"},{"qty":100,"price":"$3.09210","currency":"USD"},{"qty":250,"price":"$2.93356","currency":"USD"},{"qty":500,"price":"$2.63226","currency":"USD"},{"qty":1000,"price":"$2.21998","currency":"USD"},{"qty":2500,"price":"$2.10898","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX20019-MAX20020.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX20019ATBA/V+T have synchronous rectification?","answer":"No. Synchronous rectification is not implemented, so an external Schottky diode is required per output channel for the low-side rectifier function."},{"question":"What is the output current of MAX20019ATBA/V+T?","answer":"Each of the two outputs is rated for 500 mA continuous current, providing a combined 1 A total output capability from the dual channels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX20019ATBA-VT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX20019ATBA-VT when reusing this data.
