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 | BOOST | passive | Bootstrap capacitor connection for the internal floating high-side N-channel MOSFET gate driver. An external CBOOST (typ. 100 nF) is tied between BOOST and SW; a boost-blocking diode (e.g. 1N4148) from VOUT charges CBOOST when SW is low. The BOOST-SW voltage must remain between 3.0 V and 5.5 V and is limited to 6.0 V absolute maximum. |+| 2 | GND | power_in | Device ground return for the analog control circuitry and the low side of the input capacitor. Must be connected to the system ground plane close to the input capacitor. |+| 3 | VFB | input | Feedback input to the internal error amplifier. Regulated to VREF = 0.800 V (0.784-0.816 V) via an external resistor divider from VOUT (RTOP to VOUT, RBOT to GND). Absolute maximum -0.5 V to 6.0 V; input bias ±10 nA typical. |+| 4 | EN | input | Enable input. Drive above VIH = 1.4 V to turn the regulator on (internal soft-start ~300 µs); drive below VIL = 0.4 V to place the device in shutdown (IQ ~7 µA). Absolute maximum -0.5 V to (VIN + 0.3 V); leakage 0.05 µA typ at VEN = 12 V. |+| 5 | VIN | power_in | Input supply. 4.7 V to 36 V for the MCP16301H (4.0 V to 30 V for the MCP16301). UVLO turns the device on at ~3.5 V rising and off at ~3.0 V falling. Bypass to GND with a low-ESR ceramic input capacitor (10 µF typical) close to the pin. Absolute maximum 40 V referenced to SW. |+| 6 | SW | output | Switch node - source of the integrated high-side N-channel MOSFET and cathode of the external freewheeling Schottky diode. Connect to the external inductor and the low side of the boost capacitor. Carries the chopped inductor current (up to 1.3 A peak current limit); route as a short, wide trace to minimize EMI. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `MCP16301T-I/CHY`+- `MCP16301T-IMCP16301HT-I/CHY`++## CAD (KiCad official)++- Symbol: `MCP16301T-I`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Microchip datasheet](docs/mcp16301t-i-datasheet.pdf) (40 pp, sha256 `47e492312d19381e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
