TPS53511RGTR from Texas Instruments, in a QFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VFB | input | Converter feedback input; connect to output voltage resistor divider; VFB threshold 765 mV (typ) in continuous mode. |
| 2 | VREG5 | power_out | Internal 5.5-V LDO power supply output; connect a 1-µF ceramic capacitor to GND; output voltage 5.3-5.7 V, max output current 70 mA. |
| 3 | SS | bidirectional | Soft-start control pin; connect an external capacitor to GND to set soft-start time; charge current 1.4-2.6 µA, discharge current 0.1-0.2 mA. |
| 4 | GND | power_in | Signal ground reference; connect strongly to PGND near the device. |
| 5 | PG | output | Open-drain power-good output; asserts high when VFB is within ±10% of target; sink current 2.5-5.0 mA at VPG = 0.5 V. |
| 6 | EN | input | Enable control input; logic high (≥1.5 V) enables the converter, logic low (≤0.4 V) shuts it down; max input voltage 18 V. |
| 7 | PGND | power_in | Power ground return for low-side MOSFET; also serves as current comparator input; connect strongly to GND near the device. |
| 8 | PGND | power_in | Power ground return for low-side MOSFET; also serves as current comparator input; connect strongly to GND near the device. |
| 9 | SW | bidirectional | Switch node between high-side and low-side N-channel FETs; also serves as current comparator input; DC range -1.8 V to 18 V, transient <10 ns -3 V to 18 V. |
| 10 | SW | bidirectional | Switch node between high-side and low-side N-channel FETs; also serves as current comparator input; DC range -1.8 V to 18 V, transient <10 ns -3 V to 18 V. |
| 11 | SW | bidirectional | Switch node between high-side and low-side N-channel FETs; also serves as current comparator input; DC range -1.8 V to 18 V, transient <10 ns -3 V to 18 V. |
| 12 | VBST | power_in | Bootstrap supply input for high-side N-channel FET gate driver; connect a 0.1-µF ceramic capacitor from this pin to SW; internal PN diode from VREG5 to VBST; max voltage 26 V (abs), 5.7 V with respect to SW (recommended). |
| 13 | VIN | power_in | Power input connected to high-side N-channel FET drain; recommended operating range 2.0-18.0 V; max 20 V absolute. |
| 14 | VIN | power_in | Power input connected to high-side N-channel FET drain; recommended operating range 2.0-18.0 V; max 20 V absolute. |
| 15 | VCC | power_in | Supply input for internal 5-V linear regulator for control circuitry; recommended operating range 4.5-18.0 V; operating supply current 850-1300 µA, shutdown current <10 µA. |
| 16 | VO | input | Connect to converter output voltage node; used for adaptive on-time adjustment; max voltage 5.5 V (recommended). |
| 17 | PowerPAD | power_in | Exposed thermal pad; must be soldered to PCB for thermal and mechanical performance; must be connected to PGND; θJCbot = 3.9 °C/W. |
