That 65 V ceiling covers 48 V nominal telecom supplies with margin for transients, and the 3 V minimum lets it start from a deeply-discharged 12 V battery or a 5 V pre-regulated rail. The 600 mA continuous output suits sensor modules, I/O isolators, and auxiliary housekeeping rails in motor drives or PLC racks where the main load is a few hundred milliamps. The synchronous rectifier keeps efficiency above 90 % down to light loads, which matters when the converter idles between burst reads from a fieldbus transceiver. ## Switching frequency and thermal envelope At the low end you minimise switching losses for a 48 V input; at the high end you shrink the inductor to 2.2 µH or 3.3 µH, which fits the 2×2 mm package profile. The 150 °C junction temperature rating gives headroom in a sealed enclosure with 85 °C ambient and no forced air — the thermal pad under the 9-VQFN-HR carries the heat into the PCB copper pour. The fixed 5 V output eliminates the feedback divider and the associated noise injection on the sense node — one less component to place in the tight layout around the 2 mm QFN. The 9-VQFN-HR (2×2 mm) package with wettable flanks supports automated optical inspection (AOI) of the solder joints — no hidden fillets under the body. The exposed thermal pad is on the bottom; the recommended PCB land pattern includes a 2.2×2.2 mm thermal pad with at least four vias to the inner ground plane. Available in Tape & Reel (TR) and Cut Tape (CT) options for prototype or production quantities.","metaTitle":"TI LMR36506R5RPER 5V 600mA Buck Converter, 65V Input, 9-VQFN","metaDescription":"Texas Instruments LMR36506R5RPER step-down regulator: 3V-65V input, 5V fixed 600mA output, 200kHz-2.2MHz switching, synchronous rectifier, -40°C to 150°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"9-VFQFN","lifecycle_stage":"eol_hot","Current - Output":"600mA","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"200kHz ~ 2.2MHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"65V","Voltage - Input (Min)":"3V","Supplier Device Package":"9-VQFN-HR (2x2)","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.15","priceTiers":[{"qty":1,"price":"$4.15000","currency":"USD"},{"qty":10,"price":"$3.72600","currency":"USD"},{"qty":25,"price":"$3.52240","currency":"USD"},{"qty":100,"price":"$3.05270","currency":"USD"},{"qty":250,"price":"$2.89616","currency":"USD"},{"qty":500,"price":"$2.59872","currency":"USD"},{"qty":1000,"price":"$2.19170","currency":"USD"},{"qty":3000,"price":"$2.08211","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d5e2dce30c3bd54f796bdb0903de8f39.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMR36506R5RPER/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source to LMR36506R5RPER?","answer":"The LMR36506RF3RPER is the same 600 mA synchronous buck converter in the same 9-VQFN-HR package, but with a fixed 3.3 V output instead of 5 V. The pinout and footprint are identical — the only difference is the output voltage set by the internal feedback.

The only change is the output voltage — 5 V vs 3.3 V — so the load circuitry must be rated for 5 V.
