It switches at 2.25 MHz, which lets the output filter use smaller inductors and capacitors than a 500 kHz part — a real board-space saver in ECU modules where every mm² counts. ## Input Range and Thermal Margin Input voltage range is 2 V to 6 V, so it runs comfortably from a 3.3 V or 5 V rail — the 3.3 V input question is straightforward: yes, 3.3 V sits well inside the operating window. If your design sees junction temperatures above that, look at the LM53625LQURNLRQ1 which rates to 150°C junction. The datasheet layout recommendation calls for a 2x2 array of 0.3 mm vias — skip them and the thermal resistance climbs. The WSON is a QFN-style package; rework requires a hot-air nozzle that covers the whole body, not just one side. That means no last-time-buy scramble for this BOM line. Texas Instruments lists it as ROHS3 compliant.","metaTitle":"TPS62261TDRVRQ1 Buck Converter 600mA 2.25MHz Automotive","metaDescription":"TPS62261TDRVRQ1 from Texas Instruments — step-down buck regulator, 600 mA output, 2.25 MHz switching, fixed 1.8 V, AEC-Q100, -40°C to 105°C.

Electrically they share the same 600 mA output, 2.25 MHz switching, and fixed 1.8 V output. If your application does not require automotive grade, the DRVR is a lower-cost alternative; if it does, the TDRVRQ1 is the correct choice."},{"question":"Can TPS62261TDRVRQ1 operate from a 3.3V input?","answer":"Yes. The input voltage range is 2 V to 6 V. A 3.3 V rail sits well within the operating window. At 3.3 V in and 1.8 V out the duty cycle is about 55 %, well within the buck converter's stable range."},{"question":"What is the closest functional second-source to TPS62261TDRVRQ1?","answer":"The LM53625LQURNLRQ1 from Texas Instruments is a close functional peer — also AEC-Q100, buck topology, fixed output, synchronous rectifier, and 2.1 MHz switching. The main difference is output current: the LM53625 delivers 2.5 A versus 600 mA for the TPS62261. If your load is under 600 mA, the TPS62261 is the tighter fit; for higher loads the LM53625 is the natural upgrade."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62261TDRVRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62261TDRVRQ1 when reusing this data.
