TPS563201 3A Buck Regulator

@@ -0,0 +1,49 @@+# TPS563201++**Texas Instruments** · Switching Regulator (Buck) · SOT-23-6++The TPS563201 is a 3 A synchronous step-down (buck) converter with both high-side and low-side MOSFETs integrated. It uses D-CAP2 control for fast transient response with low external part count, converting a 4.5 V to 17 V input to output rails down to 0.76 V. The SOT-23-6 package suits point-of-load supplies on dense boards.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground pin. Source terminal of the low-side power NFET as well as the ground return for the controller circuit. Connect sensitive VFB to this GND at a single point. |+| 2 | SW | output | Switch node output. Connection point between the high-side and low-side NFETs; connects to the external inductor. Absolute-max range −2V to 19V. |+| 3 | VIN | power_in | Input voltage supply pin. Drain terminal of the high-side power NFET. Operating range 4.5V to 17V (abs-max 19V). |+| 4 | VFB | input | Converter feedback input. Connect to the output voltage through a feedback resistor divider; internal reference is 0.768V nominal (2% accuracy at 25°C). Abs-max 6V. |+| 5 | EN | input | Enable input control. Active high; must be pulled up to enable the device. Do not float. Operating range 0 to 17V (abs-max 19V). |+| 6 | VBST | power_out | Bootstrap supply input for the high-side NFET gate-drive circuit. Connect a 0.1µF ceramic capacitor between VBST and SW pins. Abs-max 25V (27V for 10ns transients); 6V referenced to SW. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Synchronous buck (step-down) converter |+| Output current | 3 A |+| Input voltage | 4.5 V to 17 V |+| Output voltage | 0.76 V to ~7 V (adjustable) |+| Switching frequency | 580 kHz typ |+| Control | D-CAP2 (fast transient) |+| Operating temperature | -40 C to 125 C (junction) |++## Ordering variants++- `TPS563201DDCR`+- `TPS563201DDCT`++## CAD (KiCad official)++- Symbol: `tps563201.kicad_sym`+- Footprint: `tps563201.kicad_mod`+- 3D model: SOT-23-6 body from KiCad `Package_TO_SOT_SMD/SOT-23-6`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps563201.pdf) (30 pp, sha256 `9ec97e2062d5fba1`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
