It uses synchronous rectification for efficiency and switches at 600 kHz, allowing a small inductor and output capacitor. The output is adjustable from 0.5 V up to 5 V, with an input range of 4.7 V to 14 V — suited for 5 V and 12 V rails in industrial, telecom, and automotive auxiliary supplies. ## Package and rework considerations The part comes in a 15-FLGA package (PG-LGA-15-1), a land-grid array with no external leads. It is surface-mount only. For the rework bench, the LGA has a central thermal pad that needs a good via stitch to the ground plane — without it the junction climbs fast above 3 A continuous. The land pattern is compact, so a stencil with 0.1 mm thickness and a reflow profile matching the solder paste's datasheet gives consistent fillets. No external compensation network needed — the internal loop is stable with the recommended output capacitor values. ## Temperature range and deployment The 125°C junction limit means derating the output current above 85°C ambient — the thermal resistance of the LGA package is the constraint, not the silicon. For a 12 V in, 3.3 V out at 4 A, expect the junction to run about 30°C above ambient with a good PCB heatsink. No AEC-Q grade is stated, so qualification for automotive safety-critical paths would need additional testing. ## Lifecycle and sourcing ROHS3 compliant. No official second-source or pin-compatible cross-reference is listed in the supply record, so dual-sourcing would require evaluating a functionally equivalent buck converter from another vendor with similar input range, output current, and switching frequency.","metaTitle":"TDM3883XUMA1 4A Buck Regulator, 15-FLGA, -40°C to 125°C","metaDescription":"TDM3883XUMA1 is a step-down buck regulator with 4A output, 600kHz switching, adjustable output from 0.5V to 5V.
