With a supply range of 5.5 V to 28 V on Vcc/Vdd, it handles common intermediate rails from 12 V to 24 V in notebook, desktop, and industrial power systems. The two independent outputs share a single 24-VFQFN exposed-pad package (24-VQFN 4x4 mm), keeping the footprint compact for dense PCB layouts. ## Where the D-CAP™ series fits D-CAP™ is TI's proprietary constant-on-time control architecture that delivers fast transient response without external compensation — the loop stability is built into the on-time generator, so the BOM omits the usual RC network around the error amplifier. Control features include Enable, On Time Control, and Power Good — the Power Good flag can sequence downstream converters or feed a system supervisor without an external comparator.","metaTitle":"TPS51125ARGET Texas Instruments D-CAP™ Buck Controller, 28V","metaDescription":"Texas Instruments TPS51125ARGET D-CAP™ dual-output step-down controller. 5.5V-28V supply, 24-VQFN, active production.

The TPS51125ARGET has a higher maximum supply (28 V vs 4.5 V min) and adds Power Good output, so a direct drop-in depends on the supply rail voltage and whether the PG flag is used."},{"question":"What compliance documentation does Texas Instruments provide for TPS51125ARGET?","answer":"The part is RoHS3 compliant (ROHS3 Compliant per).
