That current rating in this footprint means the thermal design — copper area on the PCB, airflow, ambient temperature — is the limiting factor, not the silicon itself. ## D-CAP2 control and 500 kHz switching The D-CAP2 architecture provides fast transient response without external compensation — the loop bandwidth tracks the output capacitor ESR, so the output voltage recovers from a load step within a few switching cycles. The Eco-Mode feature drops the switching frequency at light load to maintain efficiency below 100 mA, which matters for always-on subsystems in battery-powered equipment. The synchronous rectifier eliminates the external Schottky diode — the internal low-side FET handles the freewheeling current. This saves a component and a PCB placement, but the inductor must be rated for the 5 A DC plus the peak-to-peak ripple current at 500 kHz; a 20% to 30% ripple ratio keeps the output voltage ripple below 10 mV with ceramic output capacitors.","metaTitle":"TPS565201DDCT 5A Buck Regulator, D-CAP2, TSOT-23-6","metaDescription":"Texas Instruments TPS565201DDCT step-down regulator, 5 A output, 4.5-17 V input, 500 kHz switching, D-CAP2 control.
