Product Overview
TPS563201DDCR is a Texas Instruments synchronous step-down voltage regulator for Power_Management designs requiring conversion from a 4.5-17 V recommended input supply to a regulated 0.76-7 V output. The integrated synchronous buck converter supports 3 A output current and uses D-CAP2 control for fast transient response without external compensation components.
The device is supplied in a DDC, 6-pin SOT package measuring 1.6 mm × 2.9 mm. Its pinout includes GND, SW, VIN, VFB, EN, and VBST. VIN serves as the input voltage supply and high-side NFET drain terminal, SW is the switch node, VFB accepts the resistor-divider feedback signal, and VBST supplies the high-side NFET gate drive through a 0.1 µF capacitor to SW.
Electrical and protection characteristics include 580 kHz switching frequency under the specified VIN=12 V, VO=3.3 V, IO=1 A condition, 95 mΩ typical high-side resistance, 57 mΩ typical low-side resistance, 1.0 ms internal soft start, hiccup protection, VIN UVLO thresholds, and 172°C typical thermal shutdown. The recommended operating junction temperature range is -40°C to 125°C.
