It's designed for high-current, high-frequency switching applications such as server and telecom DC-DC converters, point-of-load regulators, and motor-drive inverter stages where board space is tight and thermal performance matters. The 4.25V to 16V supply range covers common intermediate bus and logic rails, and the -40°C to 125°C junction temperature rating suits it for industrial and automotive environments that see temperature cycling. ## Supply voltage and temperature — what they mean for your design The 4.25V to 16V supply range means this part can run from a 5V or 12V rail without an extra regulator, simplifying the power tree. The -40°C to 125°C junction temperature range covers cold-crank and under-hood conditions, so it's a candidate for automotive auxiliary loads or industrial drives that see ambient heat. If your design lives in a controlled 0°C to 70°C environment, the margin is generous — but the real value is in applications where the PCB sees wide swings. ## Package and footprint — layout considerations The 25-PowerTFQFN package (PG-IQFN-25-1) is a surface-mount, thermally enhanced QFN with an exposed pad. The thermal pad needs a via array to the ground plane to pull heat out of the junction; without it, the 125°C rating is academic at high current. The 25-pin count keeps routing manageable — the power stage output and supply pins are typically on opposite sides, so plan the decoupling caps and output inductor placement before you route. ## Lifecycle and compliance — sourcing posture The TDA21520AUMA1 is listed as Active in the lifecycle status and is ROHS3 compliant.","metaTitle":"TDA21520AUMA1 Infineon EiceDRIVER™ Power Stage, 4.25V-16V","metaDescription":"Infineon TDA21520AUMA1 EiceDRIVER™ power stage driver, 4.25V~16V supply, -40°C~125°C, PG-IQFN-25-1.
