Descripción general

Description

LNK3205G-TL is an offline switch-mode power-supply controller from Power Integrations’ LinkSwitch-TN family. It integrates a high‑voltage MOSFET and control circuitry for simple, low‑power flyback converters.
Key points:
- Purpose: for universal-input (AC) offline power supplies such as wall adapters, phone chargers, and small LED drivers.
- Core features: primary-side regulation option (reduces or eliminates opto-isolator feedback), fixed-frequency current‑mode control, built‑in protections (overcurrent/short-circuit, thermal), and low standby power with minimal external components.
- Packaging: -TL indicates Tape & Reel; G denotes Pb‑free/Green variant.
- Benefits: simplified BOM, small footprint, faster design cycles, and good EMI characteristics.
Typical use: a compact, cost-effective offline supply delivering a few watts to a few tens of watts, depending on your topology and components.

Features

Here are the key features of LNK3205G-TL:
- Integrated 700V high-voltage MOSFET
- Primary-Side Regulation (PSR) — no opto-isolated feedback
- Fixed-frequency flyback controller
- Up to ~5W output power in a compact design
- Wide universal input range (typical 85–265 VAC)
- Very low standby power
- Cycle-by-cycle current limiting
- Protection: overcurrent, thermal shutdown, and fault protection
- Minimal external components required
- Packaging: 8-pin (DIP/SOIC), TL = tape-and-reel, RoHS-compliant
Suitable for simple, efficient offline flyback power supplies (e.g., wall adapters, USB chargers).

Package

LNK3205G-TL comes in an 8-pin surface-mount SO-8 package (SOP-8), with Tape & Reel (TL) packaging; RoHS-compliant.

Pinout

- Pin count: 8 pins (DIP-8/SO-8 package).
- Function: LNK3205G-TL is an offline switcher IC with an integrated high-voltage MOSFET for flyback power supplies. It provides primary-side regulation for isolated SMPS, enabling a compact, resistorless feedback path in many designs.

Manufacturer

- Manufacturer: Power Integrations.
- What kind of company: A fabless semiconductor company that designs and markets high-voltage, high-efficiency switch-mode power supply ICs for energy-efficient power converters (e.g., adapters, chargers, SMPS).

Application

Applications of LNK3205G-TL:
- Off-line AC-DC flyback converters for low-power SMPS (≈5W)
- Universal-input wall adapters and USB/mobile device chargers
- Compact standby/power-supply modules for consumer electronics
- Simple LED-driver power supplies requiring low-cost, high-volume production
