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 | IN | power_in | Power input that connects to the DRAIN of the internal FET; this is the same IN net as pin 2. |+| 2 | IN | power_in | Power input that connects to the DRAIN of the internal FET. |+| 3 | B_GATE | output | Blocking FET gate driver output; connect to the GATE of the external NFET, and leave floating if no external FET is used. |+| 4 | DRV | output | Blocking FET fast pulldown switch drive; connect to the GATE of the external pulldown switch, and leave floating if no external N-FET is used. |+| 5 | IN_SYS | power_in | Power input and supply voltage of the device; connect to the source of the blocking FET when one is used, or short to IN when it is not. |+| 6 | UVLO | input | Input for setting the programmable undervoltage lockout threshold; an undervoltage event turns off the internal FET and asserts FLT, and connecting to GND selects the internal default threshold. |+| 7 | PLIM | input | Output power limit threshold input for TPS26633; connect a resistor from PLIM to GND to set the output power limit, or connect PLIM to GND if the feature is not used. |+| 8 | GND | power_in | Connect to system ground. |+| 9 | dVdT | bidirectional | A capacitor from this pin to GND sets the output voltage slew rate. |+| 10 | ILIM | bidirectional | A resistor from this pin to GND sets the overload and short-circuit current limit. |+| 11 | MODE | input | Mode selection pin for overload fault response. |+| 12 | SHDN | input | Shutdown pin; pulling SHDN low puts the device into low-power shutdown mode, and cycling SHDN resets the device after a latched fault. |+| 13 | IMON | output | Analog current monitor output that sources a scaled-down ratio of the FET current through a resistor to GND; leave floating if unused. |+| 14 | FLT | output | Open-drain fault event indicator output; leave floating or connect to GND if unused. |+| 15 | PGTH | input | PGOOD comparator input. |+| 16 | PGOOD | output | Active-high power-good output that goes high when PGTH crosses V(PGTHR) and the internal FET is enhanced, and goes low when V(PGTH) hits V(PGTHF); connect to GND or leave floating if unused. |+| 17 | OUT | power_out | Power output of the device. |+| 18 | OUT | power_out | Power output of the device. |+| 19 | N.C | unconnected | No connect. |+| 20 | N.C | unconnected | No connect. |+| 21 | N.C | unconnected | No connect. |+| 22 | N.C | unconnected | No connect. |+| 23 | N.C | unconnected | No connect. |+| 24 | N.C | unconnected | No connect. |+| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-24(4x4) |+| Category | Circuit Protection |+| Pins | 25 |++## CAD (KiCad official)++- Symbol: `TPS26633RGET`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.7x2.7mm`+- 3D model: VQFN-24(4x4) (KiCad packages3D, STEP)+- 3D model files: `tps26633rget-etched.step` / `tps26633rget-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps26633rget.step` / `tps26633rget.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/tps2663) (60 pp, sha256 `63ce6e9453e4499b`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
