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 and line undervoltage sense. Internal source follower clamps at ~1.2 V; threshold current 75-115 uA disables switching (ON/OFF control). An external resistor from the DC line can be tied here to enable line UV sense (>25 uA to initiate switching). |+| 2 | BP/M | power_in | BYPASS/MULTI-FUNCTION pin. Connection for external bypass capacitor for internally generated 5.85 V supply. Capacitor value also selects current limit (0.1 uF = standard, 1 uF = reduced, 10 uF = increased). A 6.4 V shunt clamp allows OVP latch shutdown when current into pin exceeds ISD. |+| 4 | D | power_in | DRAIN pin of the integrated 725 V power MOSFET. Provides internal operating current for both start-up and steady-state operation via the internal high-voltage current source to the BP/M capacitor. Connects to the transformer primary in a typical flyback topology. |+| 5 | S | power_in | SOURCE pin. Internally connected to the output MOSFET source for high-voltage power return and control-circuit common. Pins 5, 6, 7, 8 are all SOURCE (tied together internally) and simplify heat sinking to the PCB. |+| 6 | S | power_in | SOURCE pin. Internally tied to the MOSFET source; serves as power return and PCB thermal path. |+| 7 | S | power_in | SOURCE pin. Internally tied to the MOSFET source; serves as power return and PCB thermal path. |+| 8 | S | power_in | SOURCE pin. Internally tied to the MOSFET source; serves as power return and PCB thermal path. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | POWER INTEGRATIONS |+| Package | DIP-8C |+| Category | PMIC |+| Pins | 7 |++## Ordering variants++- `TNY288PGP`+- `TNY288PGPG`+- `TNY288PGD`+- `TNY288PGDG`+- `TNY288PGK`+- `TNY288PGKG`++## CAD (KiCad official)++- Symbol: `TNY288PG`+- Footprint: `Package_DIP:DIP-8_W7.62mm`+- 3D model: DIP-8C (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [POWER INTEGRATIONS datasheet](docs/tny288pg-datasheet.pdf) (26 pp, sha256 `9117cb81a319b0d4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
