Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | BST | passive | Bootstrap. A capacitor (0.1µF to 1µF typical) connected between SW and BST forms a floating supply across the internal power switch driver, boosting the high-side MOSFET gate above the supply voltage. |+| 2 | GND | power_in | Ground reference for the regulated output voltage and all internal control circuits. Careful PCB layout is required to minimize noise coupling into this reference. |+| 3 | FB | input | Feedback input, nominally 0.81V. Connect to the output resistor divider (or directly to VOUT for 0.81V output) to set the regulated output voltage. Includes a frequency foldback comparator that lowers the oscillator frequency to ~480kHz when FB falls below 400mV during current limit. |+| 4 | EN | input | On/Off control input. Pull above 1.2V to enable the converter and below 0.4V to disable it. Do not leave floating; if unused, tie to VIN through a 100kΩ resistor. |+| 5 | IN | power_in | Supply voltage input, 4.75V to 24V (absolute maximum 26V). A local decoupling capacitor (C1) is required close to the pin to prevent large voltage spikes at the input. |+| 6 | SW | power_out | Switch output from the internal high-side MOSFET (RDS(on) ~0.35Ω, current limit ~2.4A). Connects to the external inductor and catch diode; also the reference return for the BST floating supply capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-26 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `AP5100WG-7WG-7`++## CAD (KiCad official)++- Symbol: `AP5100WG-7`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-26 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP5100WG-7.pdf) (12 pp, sha256 `cc0494aed30da802`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
