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 | EN/UV | input | Enable / Undervoltage input. Dual-function pin: enable input (ON/OFF control, threshold current 75-115 uA) and line undervoltage sense through an external resistor to the DC line. Internal source follower clamps output at ~1.2 V; sinks up to 115 uA. |+| 2 | BP/M | power_out | Bypass / Multi-function pin. Connection for external bypass capacitor for the internally generated 5.85 V supply; capacitor value (0.1 uF / 1 uF / 10 uF) selects the current-limit level. Also provides shutdown when current exceeds ISD and supports OVP via a Zener from a bias winding (6.4 V shunt clamp). |+| 4 | D | power_in | DRAIN. Power MOSFET drain connection (725 V rated). Provides internal operating current for both start-up and steady-state operation via an internal high-voltage current source that charges the BP/M capacitor when the MOSFET is off. |+| 5 | S | power_in | SOURCE. Internally connected to the output MOSFET source for high-voltage power return and control-circuit common. Multiple SOURCE pins are tied together internally and used as the primary heat-sinking path to the PCB. |+| 6 | S | power_in | SOURCE. Internally connected to the output MOSFET source for high-voltage power return and control-circuit common. Electrically quiet SOURCE pins simplify heat sinking to the PCB for low EMI. |+| 7 | S | power_in | SOURCE. Internally connected to the output MOSFET source for high-voltage power return and control-circuit common. |+| 8 | S | power_in | SOURCE. Internally connected to the output MOSFET source for high-voltage power return and control-circuit common. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | POWER INTEGRATIONS |+| Package | SO-7 |+| Category | PMIC |+| Pins | 7 |++## Ordering variants++- `TNY285DG-TL`+- `TNY285DG-TLPG`+- `TNY285DG-TLPN`+- `TNY285DG-TLKG`+- `TNY285DG-TLKG-TL`++## CAD (KiCad official)++- Symbol: `TNY285DG-TL`+- Footprint: `Package_SO:TI_SO-PowerPAD-8`+- 3D model: SO-7 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [POWER INTEGRATIONS datasheet](docs/tny285dg-tl-datasheet.pdf) (26 pp, sha256 `9117cb81a319b0d4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
