The integrated synchronous rectifier improves efficiency over a diode-based buck — expect lower conduction loss at high output current, which matters when the 3 A rating is used near its ceiling in a thermally constrained layout. ## 700 kHz switching — inductor size vs efficiency trade-off Switching at 700 kHz lets the designer use a physically smaller inductor than a 300 kHz part, at the cost of slightly higher switching losses. The 3 A output with synchronous rectification keeps the efficiency curve competitive in the 5 V-to-3.3 V and 5 V-to-1.8 V conversion sweet spots. The adjustable output range (0.808 V minimum, 4.5 V maximum) covers the common core and I/O voltages for FPGAs, MCUs, and SoCs — the 0.808 V floor accommodates the latest low-voltage logic rails. ## Junction temperature range and package thermal path ROHS3 compliant — no exemption-based restrictions on the bill of materials for EU or global markets.","metaTitle":"TPS5432DDAR Texas Instruments Buck Converter, 3 A, 700 kHz","metaDescription":"Active-production step-down converter from TI. 3 A output, 2.95-6 V input, 700 kHz switching, synchronous rectification. -40 to +125°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-PowerSOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"700kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.95V","Voltage - Output (Max)":"4.5V","Supplier Device Package":"8-SO PowerPad","Voltage - Output (Min/Fixed)":"0.808V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.92000","currency":"USD"},{"qty":10,"price":"$0.80800","currency":"USD"},{"qty":25,"price":"$0.75920","currency":"USD"},{"qty":100,"price":"$0.61950","currency":"USD"},{"qty":250,"price":"$0.57544","currency":"USD"},{"qty":500,"price":"$0.48972","currency":"USD"},{"qty":1000,"price":"$0.39178","currency":"USD"},{"qty":2500,"price":"$0.35505","currency":"USD"},{"qty":5000,"price":"$0.34650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3b4b5b6516ef2bd7496e262834fe273e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does TPS5432DDAR compare to TPS65261RHBT as a second-source?","answer":"TPS65261RHBT is a triple-output buck (3 channels at 3 A each) versus the single-output TPS5432DDAR.
