The 3V to 5.5V input range directly regulates from 3.3V or 5V rails, and the adjustable output from 0.6V to 4.5V covers core voltages for FPGAs, MCUs, and I/O banks. ## 6-WSON exposed pad — rework and thermal reality The exposed pad also means the part sits flush against the board; a hot-air rework station with a 3x3 mm nozzle lifts it cleanly if the board has been baked per J-STD-033 for moisture sensitivity. ## No synchronous rectifier — plan for the Schottky The LMR10520YSD/NOPB uses an external Schottky catch diode instead of an integrated synchronous FET. This keeps the BOM cost low and avoids the shoot-through risk of a high-side/low-side pair, but efficiency at output voltages below 1.8V drops compared to a synchronous part — expect around 85% efficiency at 1.2V out, 2A in. The external diode also adds a layout constraint: the diode loop from switch node to ground must be under 10 mm to keep ringing below the 5.5V abs-max rating.","metaTitle":"TI LMR10520YSD/NOPB SIMPLE SWITCHER Buck, 2A, 3MHz","metaDescription":"Texas Instruments LMR10520YSD/NOPB SIMPLE SWITCHER step-down regulator, 2A output, 3MHz switching, 6-WSON package.

It does not drop into the same board as the LMR10520YSD/NOPB because the pinout, package (32-QFN vs 6-WSON), and supply rails differ. For a single-output 2A non-synchronous replacement, stay within the SIMPLE SWITCHER family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMR10520YSD-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMR10520YSD-NOPB when reusing this data.
