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 | S | power_in | Power MOSFET source connection. Also the ground reference for the BYPASS and FEEDBACK pins. Multiple SOURCE pins are tied together internally and should be soldered to a sufficient copper area for thermal dissipation (kept at or below 100 °C). |+| 2 | S | power_in | Power MOSFET source connection (tied to other SOURCE pins internally). Serves as the ground reference for the BP and FB pins and as the primary thermal path. |+| 3 | BP | power_in | BYPASS pin. Connection point for a 0.1 µF external bypass capacitor to the internally generated 5.8 V supply. Undervoltage disables the MOSFET below 4.8 V; a 6.3 V shunt clamps the pin. If an external bias winding is used, current into BP must not exceed 1 mA. |+| 4 | FB | input | FEEDBACK pin. ON/OFF control input; MOSFET switching for the next cycle is disabled when the current delivered into this pin exceeds the ~49 µA logic-high threshold (V_FB ≈ 1.63 V for LNK363/364). Sampled at the start of each oscillator cycle. |+| 5 | D | power_in | DRAIN pin. High-voltage (700 V BV_DSS) power MOSFET drain connection to the transformer primary. Also supplies internal operating current for both startup and steady-state via an integrated high-voltage current source, eliminating the need for a bias winding. |+| 6 | S | power_in | Power MOSFET source connection (tied to other SOURCE pins internally). Note: on the DIP-8B outline, pin 6 is often omitted on Power Integrations parts to provide HV creepage between DRAIN (pin 5) and SOURCE; verify against the package drawing. |+| 7 | S | power_in | Power MOSFET source connection (tied to other SOURCE pins internally). Ground reference for BP/FB and primary thermal path. |+| 8 | S | power_in | Power MOSFET source connection (tied to other SOURCE pins internally). Ground reference for BP/FB and primary thermal path. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | POWER INTEGRATIONS |+| Package | DIP-8B |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `LNK364PNP`+- `LNK364PNPN`+- `LNK364PNG`+- `LNK364PNGN`+- `LNK364PND`+- `LNK364PNDN`++## CAD (KiCad official)++- Symbol: `LNK364PN`+- Footprint: `Package_DIP:DIP-8_W7.62mm`+- 3D model: DIP-8B (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [POWER INTEGRATIONS datasheet](docs/lnk364pn-datasheet.pdf) (16 pp, sha256 `650ad03ed20c90e2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
