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 | CS1 | output | Sets the channel 1 overcurrent (OCL) trip level; CS1 sources about 10 µA, and the CS1 voltage must be set between 0.2 V and 2 V over all operating temperatures through a resistor to GND. |+| 2 | VFB1 | input | Channel 1 voltage feedback input for the output regulation and OVP/UVP monitoring. |+| 3 | VREG3 | power_out | 3.3-V LDO output (100 mA) that supplies the analog circuitry; place a ceramic capacitor of 1 µF or larger (X5R or better) close to the pin. |+| 4 | VFB2 | input | Channel 2 voltage feedback input for the output regulation and OVP/UVP monitoring. |+| 5 | CS2 | output | Sets the channel 2 overcurrent (OCL) trip level; CS2 sources about 10 µA, and the CS2 voltage must be kept between 0.2 V and 2 V over all operating temperatures through a resistor to GND. |+| 6 | EN2 | input | Channel 2 enable input; the SMPS turns on above 1.6 V and off below 0.3 V. |+| 7 | PGOOD | output | Combined power-good open-drain output flag that must be pulled up to an external rail through a resistor. |+| 8 | SW2 | output | Channel 2 switch-node connection, which must be tied to the drain of the low-side MOSFET because it is used for inductor current sensing. |+| 9 | VBST2 | input | Bootstrap supply input for the channel 2 high-side MOSFET driver; connect a capacitor from this pin to SW2. |+| 10 | DRVH2 | output | Channel 2 high-side MOSFET gate driver output. |+| 11 | DRVL2 | output | Channel 2 low-side MOSFET gate driver output. |+| 12 | VIN | power_in | Power conversion input that must receive the same voltage as the drain of the high-side MOSFETs of both channels; the device operates from 5 V to 24 V. |+| 13 | VREG5 | power_out | 5-V LDO output (100 mA) that supplies the gate drivers; place a ceramic capacitor of 1 µF or larger (X5R or better) close to the pin. |+| 14 | VO1 | input | Channel 1 output voltage input that serves as the 5-V input for switch-over; the VREG5 switchover requires VO1 to be above VREG5 minus 1 V. |+| 15 | DRVL1 | output | Channel 1 low-side MOSFET gate driver output. |+| 16 | DRVH1 | output | Channel 1 high-side MOSFET gate driver output. |+| 17 | VBST1 | input | Bootstrap supply input for the channel 1 high-side MOSFET driver; connect a capacitor from this pin to SW1. |+| 18 | SW1 | output | Channel 1 switch-node connection, which must be tied to the drain of the low-side MOSFET because it is used for inductor current sensing. |+| 19 | VCLK | output | 260-kHz clock output for an external charge pump, available when EN1 is on and driven from VO1; leave open if unused. |+| 20 | EN1 | input | Channel 1 enable input; the SMPS turns on above 1.6 V and off below 0.3 V. |+| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WQFN-20-EP(3x3) |+| Category | Power Management (PMIC) |+| Pins | 21 |++## CAD (KiCad official)++- Symbol: `TPS51275BRUKR`+- Footprint: `Package_DFN_QFN:UQFN-20-1EP_3x3mm_P0.4mm_EP1.85x1.85mm`+- 3D model: WQFN-20-EP(3x3) (KiCad packages3D, STEP)+- 3D model files: `tps51275brukr-etched.step` / `tps51275brukr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps51275brukr.step` / `tps51275brukr.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps51275b) (32 pp, sha256 `3995a003a7a617e9`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
