The 10-VFDFN package with exposed pad is hand-solderable with a fine-tip iron or hot-air station — no reflow oven required if you're careful with the thermal pad. The 0.5 mm pitch means a basic PCB with thermal vias under the pad will do the job. ## Switching frequency and efficiency trade-offs The D-CAP2™ architecture gives fast transient response, so output capacitance can be lower than with voltage-mode controllers. The synchronous rectifier means the low-side FET replaces the external Schottky diode, boosting efficiency especially at low output voltages. Eco-Mode™ pulse-skipping keeps quiescent current down at light load — good for battery-powered or always-on circuits. ROHS3 compliant — no exemptions, so it ships into EU, UK, and other RoHS-regulated markets without paperwork headaches.","metaTitle":"TI TPS54228DRCT Buck Regulator, 2A, 700kHz, 10-VSON","metaDescription":"Active Texas Instruments TPS54228DRCT step-down regulator, 2A output, 4.5-18V input, 700kHz switching, 10-VSON package.
