Input voltage range is 2.5 V to 6 V, so it runs cleanly off a single Li-Ion cell, a 3.3 V or 5 V rail. The outputs are programmable via external resistors or fixed at 1.2 V and 1.8 V — the fixed version saves two feedback resistors on the board. ## Synchronous rectification and temperature range Both channels include synchronous rectifiers, which eliminate the external catch diode and improve efficiency at light load — expect >90 % efficiency in the mid-current range for each rail. The TPS62404QDRCRQ1 is a similar dual buck but with a 400 mA / 400 mA split and 2.3 MHz switching, also automotive-rated. If your application only needs a single 1 A rail, the TPS62824ADMQR is a single-output adjustable buck in the same package family. The base product number is TPS62421, so any cross-reference or PCN will track under that root.","metaTitle":"TPS62421DRCT Dual Buck Regulator","metaDescription":"Texas Instruments TPS62421DRCT dual step-down converter: 2.5 V to 6 V input, programmable/fixed outputs, 2.25 MHz switching, -40°C to 85°C, 10-VSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Programmable (Fixed)","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"600mA, 1A","Number of Outputs":"2","Base Product Number":"TPS62421","Output Configuration":"Positive","Frequency - Switching":"2.25MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"-","Supplier Device Package":"10-VSON (3x3)","Voltage - Output (Min/Fixed)":"1.2V, 1.8V (1.8V)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5900","priceTiers":[{"qty":1,"price":"$2.59000","currency":"USD"},{"qty":10,"price":"$2.32600","currency":"USD"},{"qty":25,"price":"$2.19440","currency":"USD"},{"qty":100,"price":"$1.86950","currency":"USD"},{"qty":250,"price":"$1.75536","currency":"USD"},{"qty":500,"price":"$1.53594","currency":"USD"},{"qty":1250,"price":"$1.27264","currency":"USD"},{"qty":2500,"price":"$1.24200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/361b6236a18c40d9978217bb9fc7818e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62421DRCT/alternatives.json"},"ai":{"faq":[{"question":"Is the TPS62421DRCT pin-compatible with the TPS62420?","answer":"The TPS62420 is the adjustable-output version of this dual buck family; the TPS62421DRCT has fixed 1.2 V and 1.8 V outputs.
