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 | SS2 | passive | Soft-start input for Buck 2; an internal 5-µA charging current sources into this pin, and a small ceramic capacitor on it sets the Buck 2 soft-start time. |+| 2 | FB2 | input | Feedback voltage input for Buck 2; a resistor divider sets 0.8 V at FB2 from the converter output to ground, and the absolute maximum voltage on this pin is -0.3 to 3.6 V. |+| 3 | EN2 | input | Enable for Buck 2: logic high enables Buck 2 and logic low disables it, with a weak internal pull-up to V5V if left open for automatic enable and a small ceramic capacitor to ground for delayed start-up; absolute maximum voltage is -0.3 to 7 V. |+| 4 | BST2 | passive | Bootstrap supply for the Buck 2 high-side gate driver, connected through a 47-nF ceramic capacitor to the LX2 switching node; BST2 is rated -0.3 to 7 V referenced to LX2. |+| 5 | VIN2 | power_in | Input supply for Buck 2 with a 10-µF ceramic capacitor placed close to this pin; operating input voltage range is 4.5 V to 18 V. |+| 6 | LX2 | output | Switching node connecting to the Buck 2 inductor; withstands -1 to 18 V transients below 10 ns. |+| 7 | LX2 | output | Switching node connecting to the Buck 2 inductor (second LX2 pin, bonded in parallel with pin 6). |+| 8 | GND | power_in | Power ground for Buck 1 and Buck 2; absolute maximum voltage range is -0.3 to 0.3 V. |+| 9 | GND | power_in | Power ground for Buck 1 and Buck 2; absolute maximum voltage range is -0.3 to 0.3 V. |+| 10 | GND | power_in | Power ground for Buck 1 and Buck 2; absolute maximum voltage range is -0.3 to 0.3 V. |+| 11 | GND | power_in | Power ground for Buck 1 and Buck 2; absolute maximum voltage range is -0.3 to 0.3 V. |+| 12 | LX1 | output | Switching node connecting to the Buck 1 inductor; withstands -1 to 18 V transients below 10 ns. |+| 13 | LX1 | output | Switching node connecting to the Buck 1 inductor (second LX1 pin, bonded in parallel with pin 12). |+| 14 | VIN1 | power_in | Input supply for Buck 1 with a 10-µF ceramic capacitor placed close to this pin; operating input voltage range is 4.5 V to 18 V. |+| 15 | BST1 | passive | Bootstrap supply for the Buck 1 high-side gate driver, connected through a 47-nF ceramic capacitor to the LX1 switching node; BST1 is rated -0.3 to 7 V referenced to LX1. |+| 16 | EN1 | input | Enable for Buck 1: logic high enables Buck 1 and logic low disables it, with a weak internal pull-up to V5V if left open for automatic enable and a small ceramic capacitor to ground for delayed start-up; absolute maximum voltage is -0.3 to 7 V. |+| 17 | FB1 | input | Feedback voltage input for Buck 1; a resistor divider sets 0.8 V at FB1 from the converter output to ground, and the absolute maximum voltage on this pin is -0.3 to 3.6 V. |+| 18 | SS1 | passive | Soft-start input for Buck 1; an internal 5-µA charging current sources into this pin, and a small ceramic capacitor on it sets the Buck 1 soft-start time. |+| 19 | COMP1 | passive | Loop compensation pin for Buck 1; a series RC network connected here compensates the control loop of this converter. |+| 20 | LOW_P | input | Low-power mode select: high enables pulse-skipping at light load for Buck 1 and Buck 2, low forces both to PWM mode; the pin must not be left open and is rated -0.3 to 7 V. |+| 21 | VCC | power_out | Internal 6.5-V power supply bias; connect a 10-µF ceramic capacitor from this pin to ground. |+| 22 | AGND | power_in | Analog ground; connect all GND pins and the power pad together, and tie AGND directly to the power pad under the IC. |+| 23 | ROSC | passive | Oscillator frequency setup; a resistor from this pin to ground sets the internal oscillator clock frequency between 300 kHz and 1.4 MHz, with a rated voltage range of -0.3 to 3.6 V. |+| 24 | COMP2 | passive | Loop compensation pin for Buck 2; a series RC network connected here compensates the control loop of this converter. |+| 25 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-24-EP(4x4) |+| Category | Power Management (PMIC) |+| Pins | 25 |++## CAD (KiCad official)++- Symbol: `TPS65270RGER`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.7x2.7mm`+- 3D model: VQFN-24-EP(4x4) (KiCad packages3D, STEP)+- 3D model files: `tps65270rger-etched.step` / `tps65270rger-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready);
