TNY285DG-TL

POWER INTEGRATIONS · AC-DC Controllers and Regulators · SO-7

TNY285DG-TL from POWER INTEGRATIONS, in a SO-7. 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.

  • Footprint: Package_SO:TI_SO-PowerPAD-8
  • 3D model: SO-7 (KiCad packages3D, STEP)
  • 3D model files: tny285dg-tl-etched.step / tny285dg-tl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tny285dg-tl.step / tny285dg-tl.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: POWER INTEGRATIONS datasheet (26 pp, sha256 9117cb81a319b0d4, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
