The 36V max input covers 24V industrial buses, 12V automotive systems with load-dump transients, and battery-powered equipment where the rail sags to 4.5V before the undervoltage lockout cuts in. A single output, positive polarity, with the output voltage set by a resistor divider on the FB pin. The integrated synchronous rectifier means no external Schottky catch diode is needed — the low-side FET handles the freewheeling current internally. This saves a diode's BOM cost, board area, and one thermal source, which matters when you're routing a 2A output in a 3x3 mm QFN footprint. Switching frequency is programmable from 400kHz to 2.2MHz via a resistor on the RT pin. At the low end you get better efficiency from smaller inductor AC losses; at the high end you shrink the inductor footprint and push switching noise above the AM band. The trade-off is switching loss in the FETs, which shows up as thermal rise at high input voltage and full load. ## Temperature grade and where it runs Rated for -40°C to 125°C ambient, this is an industrial-temperature part that also handles automotive under-hood and engine-bay environments. The 125°C ceiling means the junction can hit 150°C+ under load in a hot enclosure before the thermal shutdown trips — derate the output current if the ambient sits above 85°C in still air. The 16-WFQFN with exposed pad needs a solid thermal via array under the paddle to pull heat into the ground plane; without it the 2A rating is theoretical at elevated temperatures. ## Lifecycle and sourcing posture The MAX17632CATE+T carries an Active product status and is ROHS3 compliant.","metaTitle":"MAX17632CATE+T Buck Regulator, 36V Input, 2A Output","metaDescription":"Maxim Integrated MAX17632CATE+T step-down buck regulator, 4.5V to 36V input, 2A output, adjustable 0.9V to 32.4V, 400kHz-2.2MHz, synchronous rectifier, -40°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"16-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"400kHz ~ 2.2MHz","Operating Temperature":"-40°C ~ 125°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"36V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"32.4V","Supplier Device Package":"16-TQFN (3x3)","Voltage - Output (Min/Fixed)":"0.9V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.19","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.19000","currency":"USD"},{"qty":10,"price":"$2.86100","currency":"USD"},{"qty":25,"price":"$2.70440","currency":"USD"},{"qty":100,"price":"$2.34370","currency":"USD"},{"qty":250,"price":"$2.22352","currency":"USD"},{"qty":500,"price":"$1.99516","currency":"USD"},{"qty":1000,"price":"$1.68266","currency":"USD"},{"qty":2500,"price":"$1.59853","currency":"USD"},{"qty":5000,"price":"$1.53843","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX17632.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX17632CATE+T require an external Schottky diode?","answer":"No. The device integrates a synchronous rectifier (low-side FET), so no external catch or Schottky diode is needed for normal buck operation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX17632CATET","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX17632CATET when reusing this data.
