LNK564PN IC Off-line Switcher IC LNK 564 IC LNK564 ic LNK564PN

Product Overview

The LNK562-564 (LinkSwitch-LP) is a high-efficiency, offline switching IC designed to replace linear transformers in power supply applications. It integrates the controller and switching power MOSFET into a single device to provide a compact, low-cost solution.

Core Specifications

• Control Method: Simple On/Off control; requires no loop compensation.

• Input Range: Universal input voltage range (suitable for worldwide use).

• Protection: * Hysteretic thermal shutdown with automatic recovery.

  • Auto-restart functionality for short-circuit and open-loop fault conditions, reducing output power by over 85%.

Features

• Clampless Design: Proprietary IC adjustment and transformer construction techniques enable a "Clampless" design, reducing the number of external components.

• EMI Reduction: Frequency jittering is utilized to significantly reduce electromagnetic interference (EMI), allowing for the use of low-cost input filters.

• Safety & Reliability: * Ensures high-voltage creepage distances between the drain pin and all other pins on both the PCB and package.

  • Meets industry standards for overload and thermal protection without the need for temperature fuses or additional components often required in RCC (Ringing Choke Converter) designs.

• Transformer Technology: Proprietary E-Shield™ transformer technology eliminates the need for Y-capacitors.

Applications

• Offline Power Supplies: Used as an efficient, low-cost replacement for traditional linear transformer-based power supplies.

• General Consumer Electronics: Designed for applications requiring high bandwidth for fast, overshoot-free startup and good transient response.
