Texas Instruments · DC-DC Converters · TSOT-23-6

TPS563201DDCT from Texas Instruments, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground pin. Source terminal of the low-side power NFET and the ground return for the controller circuit. Connect sensitive VFB to this GND at a single point.
2 SW output Switch node. Connection between the high-side NFET drain-referenced source and the low-side NFET drain; connects to the external buck inductor. SW swings roughly from GND to VIN at 580 kHz.
3 VIN power_in Input voltage supply pin. Drain terminal of the high-side power NFET. Recommended input range 4.5 V to 17 V (absolute max 19 V). Bypass locally with a low-ESR ceramic capacitor.
4 VFB input Converter feedback input. Connect to the regulated output through a resistor divider to set VOUT. Internal reference ~0.768 V (continuous mode). Input current ±0.1 µA typ.
5 EN input Enable input. Active high; must be pulled up to enable the device. VIH ≥ 1.6 V, VIL ≤ 0.8 V, internal pull-down ~400 kΩ to GND. Absolute max 19 V.
6 VBST power_out Bootstrap supply for the high-side NFET gate driver. Connect a 0.1 µF ceramic capacitor between VBST and SW to develop the high-side gate drive rail.
