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 | VG | power_out | Internal voltage regulator output. Supplies power to the internal gate driver; connect a 100 nF ceramic capacitor between VG and VCC. |+| 2 | GND | power_in | Ground. Negative terminal of the input supply and reference for all internal circuits. |+| 3 | SHDN | input | Active-high shutdown input. Voltage above 2.2V (VIH) puts the part into low-current (7.5uA typ @ VCC=15V) shutdown; below 0.5V (VIL) returns to normal operation after ~13 ms delay. Do NOT drive between 0.5V and 2.2V - device state is undefined. |+| 4 | COM | passive | Frequency compensation input. External R-C network (typ. R3 with C3=10nF, plus optional C4) tied to this pin sets the closed-loop compensation zero for the error amplifier. |+| 5 | OUT | input | Output voltage sensing input. Monitors the converter output voltage (regulated internally to 5V ±1%) and is the connection point for the positive terminal of the output bypass capacitor. IOUT ~9 uA typ at VOUT=5V. |+| 6 | SW | input | Switching node sense pin. Connect to the drain of the external P-channel MOSFET / junction of the inductor and the cathode of the freewheeling diode. Voltage swings from one diode drop below GND up to VCC; used with VCC to sense inductor current (VILIM=120 mV typ). |+| 7 | VCC | power_in | Unregulated DC power supply input (4.8V to 32V operating; abs max 36V). Powers the CN5208 internal circuitry and is the current-sense reference for SW. Bypass with a low-ESR ceramic capacitor. |+| 8 | DRV | output | Gate drive output for the external P-channel MOSFET. Push-pull driver with an internal clamp limiting swing to ~8V below VCC (typ 6V peak-to-peak); tr/tf ~40 ns into a 2 nF load. VDRV low (VCC-VDRV) up to 6.3V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `CN5208`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ShangHai Consonance Elec datasheet](docs/cn5208-datasheet.pdf) (15 pp, sha256 `8c59915da09d1293`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
