概要

Description

TNY288KG-TL is a Power Integrations TinySwitch family off-line switcher IC. It combines a high-voltage MOSFET (about 650–700 V) with a PWM controller to drive flyback converters in a single chip, enabling compact, low-cost AC–DC power supplies.
Key points:
- Designed for low-power flyback supplies (wall adapters, phone chargers, LED drivers).
- Built-in startup, current limit, thermal shutdown, and fault protection.
- Fixed-frequency operation with EMI-friendly features (frequency jitter/valley switching in some variants).
- Wide input range (typical 85–265 VAC) and high efficiency, including no-load/emergency operation benefits.
- Minimal external components required.
Package: 8-pin package; “TL” denotes a specific package/lead form variant. Exact pinout and electrical specs vary by variant.
For precise electrical characteristics, pinout, and application circuits, consult the TNY288KG-TL datasheet and Power Integrations’ application notes.

Features

TNY288KG-TL features (concise):
- Integrated 700V high‑voltage MOSFET
- Primary‑side current‑mode control with valley switching for high efficiency
- Fixed switching frequency with EMI‑reducing jitter
- Soft‑start and robust protection: overcurrent, short‑circuit, thermal shutdown
- Wide input range suitable for off‑line flyback supplies (low standby power)
- Minimal external components required (compact BOM)
- Ideal for small offline SMPS, adapters, and chargers
- Packaging: 8‑pin device; TL indicates Tape & Reel availability
Note: Always verify exact specs from the datasheet for your application.

Package

It’s an 8-pin DIP (DIP-8) TinySwitch-II package, Tape‑and‑Reel (TL) version (RoHS-compliant).

Pinout

- Pin count: 8 pins (DIP-8/SO-8), TL = Tape & Reel package variant.
- Function: TinySwitch-TL device with an integrated high-voltage MOSFET for off-line flyback SMPS. Provides startup, switching control, current limit, protection (overload/thermal), and feedback via the opto-coupler on the secondary side to regulate the output.
- Typical primary-side pins (conceptual): DRAIN (HV input), SOURCE (return), FB (feedback from optocoupler), VCC (IC supply), IS (current sense/limit), GND/return; remaining pins are typically NC or reserved. For exact pin mapping, consult the TNY288KG-TL datasheet.

Manufacturer

- Manufacturer: Power Integrations.
- What kind of company: A semiconductor company that designs and markets high-voltage switching ICs and other power-management ICs for switch-mode power supplies (a fabless company that outsources fabrication).

Application

- Low-power isolated offline flyback power supplies
- Universal-input wall adapters and USB phone/tablet chargers
- Compact battery chargers
- Standby/auxiliary power for consumer electronics
- Small isolated LED driver circuits
