Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 0 | VIN | power_in | Chip power-supply input tied to the exposed thermal pad on the backside of the package. Connect to the same net as pin 1 VIN (10 V to 100 V input range) and to the ground/thermal copper pour for heat dissipation. |+| 1 | VIN | power_in | Chip power-supply input. Wide-voltage range 10 V to 100 V; bypass with a low-ESR bulk capacitor and a 0.1 µF ceramic close to the pin. |+| 2 | GND | power_in | Device ground reference. Connect to the system ground plane; tie the exposed pad copper to this net for thermal performance. |+| 3 | EN | input | Enable input, active high - drives the switching converter on. Pulling EN low fully shuts down the chip for zero standby current. |+| 4 | VIA | output | Input-voltage sense/divider output. Internally the VIN rail is fed through a resistor divider (≈450 kΩ / 15 kΩ) and brought out here for input-voltage sampling by an external MCU/ADC. |+| 5 | FB | input | Output-voltage feedback input to the internal error amplifier (VREF ≈ 1.25 V). Connect through an external resistor divider from VOUT to program the output voltage. |+| 6 | VB | passive | Bootstrap (floating) supply for the high-side MOSFET gate driver. Connect a bootstrap capacitor (typ. 0.1 µF) between VB and VS. |+| 7 | VS | output | Switch node - floating ground reference for the high-side driver and drain of the freewheeling path. Connect to the external inductor and the anode of the freewheeling Schottky (e.g. SS310); return of the bootstrap capacitor. |+| 8 | IS | input | MOS peak current-limit sense input (VREF ≈ 0.18 V). Sets cycle-by-cycle over-current protection via an external sense resistor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | EG Micro |+| Package | ESOP-8 |+| Category | PMIC |+| Pins | 9 |++## CAD (KiCad official)++- Symbol: `EG1192L`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm`+- 3D model: ESOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [EG Micro datasheet](docs/eg1192l-datasheet.pdf) (11 pp, sha256 `3a8a9fa6494f7877`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
