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 | AGND | power_in | Analog ground and return for the compensation network/output divider, slow-start capacitor, VBIAS capacitor and RT resistor; connect the PowerPAD to AGND. |+| 2 | VSENSE | input | Error amplifier inverting input, connected to the output voltage through the compensation network/output divider (absolute maximum -0.3 V to 4 V). |+| 3 | COMP | output | Error amplifier output; the frequency compensation network is connected from COMP to VSENSE. |+| 4 | PWRGD | output | Power-good open-drain output that is high when VSENSE is at or above 90% of Vref and low otherwise (absolute maximum 7 V, sink current 10 mA). |+| 5 | BOOT | passive | Bootstrap output; a 0.022 µF to 0.1 µF low-ESR capacitor from BOOT to PH generates the floating drive for the high-side FET driver. |+| 6 | PH | output | Phase output at the junction of the internal high-side and low-side power MOSFETs and the output inductor (absolute maximum -0.6 V to 10 V). |+| 7 | PH | output | Phase output at the junction of the internal high-side and low-side power MOSFETs and the output inductor (absolute maximum -0.6 V to 10 V). |+| 8 | PH | output | Phase output at the junction of the internal high-side and low-side power MOSFETs and the output inductor (absolute maximum -0.6 V to 10 V). |+| 9 | PH | output | Phase output at the junction of the internal high-side and low-side power MOSFETs and the output inductor (absolute maximum -0.6 V to 10 V). |+| 10 | PH | output | Phase output at the junction of the internal high-side and low-side power MOSFETs and the output inductor (absolute maximum -0.6 V to 10 V). |+| 11 | PGND | power_in | Power ground and high-current return for the low-side driver and power MOSFET; a single-point connection to AGND is recommended. |+| 12 | PGND | power_in | Power ground and high-current return for the low-side driver and power MOSFET; a single-point connection to AGND is recommended. |+| 13 | PGND | power_in | Power ground and high-current return for the low-side driver and power MOSFET; a single-point connection to AGND is recommended. |+| 14 | VIN | power_in | Input supply for the power MOSFET switches and internal bias regulator (3 V to 6 V recommended operating input); bypass to PGND close to the package with a low-ESR 10 µF ceramic capacitor. |+| 15 | VIN | power_in | Input supply for the power MOSFET switches and internal bias regulator (3 V to 6 V recommended operating input); bypass to PGND close to the package with a low-ESR 10 µF ceramic capacitor. |+| 16 | VIN | power_in | Input supply for the power MOSFET switches and internal bias regulator (3 V to 6 V recommended operating input); bypass to PGND close to the package with a low-ESR 10 µF ceramic capacitor. |+| 17 | VBIAS | power_out | Internal bias regulator output supplying regulated voltage to internal circuitry; bypass to AGND with a low-ESR 0.1 µF to 1.0 µF ceramic capacitor. |+| 18 | TRACKIN | input | External reference input, high-impedance input to the internal reference/multiplexer and error amplifier circuits (input range 0 V to Vref). |+| 19 | ENA | input | Enable input; logic high enables the oscillator, PWM control and MOSFET driver, while logic low disables operation and places the device in a low quiescent current state (enable threshold 1.20 V typical, absolute maximum 6 V... see review note). |+| 20 | RT | input | Frequency setting resistor input; connect a resistor from RT to AGND to set the switching frequency (absolute maximum -0.3 V to 6 V). |+| 21 | PowerPAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | HTSSOP-20-EP |+| Category | Power Supply Chip |+| Pins | 21 |++## CAD (KiCad official)++- Symbol: `TPS54380PWPR`+- Footprint: `Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm`+- 3D model: HTSSOP-20-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.2 mm nominal TSSOP height).
