The 87.5% maximum duty cycle supports moderate step-down ratios; for very low output voltages (e.g., 1.8V from 24V), the duty cycle limit is not a constraint, but the minimum off-time may set a practical lower bound on output voltage at high switching frequencies. ## Key ratings and what they mean for the BOM Switching frequency from 100kHz to 1MHz is set by a single resistor. Lower frequencies (100kHz–300kHz) reduce switching losses and ease layout but require larger magnetics; higher frequencies (500kHz–1MHz) shrink the inductor and output capacitor but increase gate-drive losses and make PCB layout more critical to avoid noise coupling. The controller does not have a clock-sync input, so multiple converters must be synchronised externally or operated with spread-spectrum if beat-frequency noise is a concern. ## Package and mounting Tape & Reel (TR) packaging is intended for automated pick-and-place assembly; Cut Tape (CT) is available for prototyping and low-volume builds. The ROHS3 compliance means the part is fully lead-free and compatible with lead-free reflow profiles. ## Lifecycle and sourcing The MAX15046BAEE+T is listed as Active in production. For dual-sourcing or supply resilience, the buyer should qualify the part directly with the manufacturer or through an authorised distributor.","metaTitle":"MAX15046BAEE+T Step-Down Buck Controller, 4.5V-40V","metaDescription":"MAX15046BAEE+T is a current-mode step-down (buck) controller with synchronous rectifier, 4.5V to 40V input, 100kHz to 1MHz switching, and -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"16-LSSOP (0.154\\\", 3.90mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Current Limit, Enable, Frequency Control, Power Good","Duty Cycle (Max)":"87.5%","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"100kHz ~ 1MHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Supplier Device Package":"16-QSOP-EP","Voltage - Supply (Vcc/Vdd)":"4.5V ~ 40V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.77","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.77000","currency":"USD"},{"qty":10,"price":"$4.28500","currency":"USD"},{"qty":25,"price":"$4.05080","currency":"USD"},{"qty":100,"price":"$3.51090","currency":"USD"},{"qty":250,"price":"$3.33080","currency":"USD"},{"qty":500,"price":"$2.98872","currency":"USD"},{"qty":1000,"price":"$2.52061","currency":"USD"},{"qty":2500,"price":"$2.39458","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX15046-MAX15046B.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the switching frequency range of MAX15046BAEE+T?","answer":"The switching frequency is programmable from 100kHz to 1MHz via an external resistor on the RT pin.
