Product Overview
The TPS564201 is a Texas Instruments synchronous step-down voltage regulator in the Power_Management category. It is specified for a recommended 4.5 to 17 V input voltage range and a 4 A output current rating, with an output voltage range from 0.76 to 7 V. The regulator uses D-CAP2 mode control, which is identified in the extracted datasheet facts as supporting fast transient response without external compensation components.
The device is offered in a DDC 6-pin SOT package with a 1.60 mm x 2.90 mm body. Pin functions include GND, SW, VIN, VFB, EN, and VBST. The VBST pin is the high-side NFET gate-drive supply input and uses a 0.1 µF capacitor between VBST and SW.
Operating parameters include 560 kHz switching frequency under VIN = 12 V, VO = 1.05 V, FCCM mode, 50 mΩ typical high-side switch resistance, and 22 mΩ typical low-side switch resistance. Protection and startup behavior include internal 1.0 ms soft-start, current limit, thermal shutdown, UVLO, output UVP, and hiccup-mode restart timing.
