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 | SYNC | input | Synchronization input that locks the oscillator to an external master frequency; it has VIH of 2 V to 5 V, VIL of 0.8 V maximum, and a minimum pulse width of 50 ns, and it must be connected to SGND if synchronization is not used. |+| 2 | RT | input | A resistor from this pin to ground sets the internal oscillator and switching frequency, with RT voltage of 2.38 V to 2.58 V (2.50 V typical) and an absolute maximum output current of 200 µA. |+| 3 | BP5 | output | 5-V reference output (4.5 V to 5.5 V at 1 mA load) that must be bypassed to ground with a 0.1-µF ceramic capacitor and may supply an external DC load of 1 mA or less. |+| 4 | EA_REF | input | Non-inverting input to the error amplifier that serves as the reference for the feedback loop, with a common-mode range of 0.2 V to 2.5 V. |+| 5 | SGND | power_in | Signal ground reference for the device; the PowerPAD heat slug must be connected to this pin or electrically isolated from all other pins. |+| 6 | SS/SD | input | Soft-start programming pin where a capacitor to ground sets the soft-start time using an internal 2.3-µA charge current, and pulling this pin low (below the 90 mV to 165 mV shutdown threshold) disables the controller. |+| 7 | VFB | input | Inverting input to the error amplifier that, in normal operation, is held equal to the EA_REF reference voltage. |+| 8 | COMP | output | Error amplifier output to the PWM comparator, with a feedback network from this pin to VFB for loop compensation; the pin is internally clamped above the peak of the ramp. |+| 9 | PGND | power_in | Power ground reference for the device that requires a low-impedance path to the source(s) of the lower MOSFET(s). |+| 10 | LDRV | output | Gate drive for the N-channel synchronous rectifier that switches from BP10 (MOSFET on) to ground (MOSFET off). |+| 11 | BP10 | output | 10-V reference (9.0 V to 10.3 V) used for synchronous rectifier gate drive that must be bypassed with a 1-µF ceramic capacitor and may supply an external DC load of 1 mA or less. |+| 12 | SW | input | Connection to the switched node of the converter used for overcurrent sensing, rated −0.3 V to 45 V (−2.5 V transient for less than 50 ns). |+| 13 | HDRV | output | Floating gate drive for the high-side N-channel MOSFET that switches from BOOST (MOSFET on) to SW (MOSFET off). |+| 14 | BOOST | output | Gate drive voltage for the high-side N-channel MOSFET that sits 9 V above the input voltage, with a 0.1-µF ceramic capacitor connected from this pin to SW. |+| 15 | VIN | power_in | Supply voltage for the device, operating over 10 V to 40 V with an absolute maximum of 45 V. |+| 16 | ILIM | input | Current-limit threshold pin where an internal 8 µA to 12 µA sink through an external resistor to VCC sets the overcurrent threshold, which is compared against the VIN − SW drop across the high-side MOSFET during conduction. |+| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | HTSSOP-16-EP |+| Category | Power Supply Chip |+| Pins | 17 |++## CAD (KiCad official)++- Symbol: `TPS40056PWPR`+- Footprint: `Package_SO:TSSOP-16-1EP_4.4x5mm_P0.65mm`+- 3D model: HTSSOP-16-EP (KiCad packages3D, STEP)+- 3D model files: `tps40056pwpr-etched.step` / `tps40056pwpr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps40056pwpr.step` / `tps40056pwpr.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/tps40056) (36 pp, sha256 `92cec24b9eb3f487`, retrieved 2026-10-08, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
