LNK564G - Energy Efficient Off-Line Switcher

Download the LNK564G datasheet PDF. This datasheet also covers the LNK562 variant, as both devices belong to the same energy efficient off-line switcher family and are provided as variant models within a single manufacturer datasheet.

General Description

LinkSwitch-LP switcher ICs cost effectively replace all unregulated isolated linear transformer based (50/60 Hz) power supplies up to 3 W output power.

For worldwide operation, a single universal input design replaces multiple linear transformer based designs.

Key Features

  • Lowest component count switcher.
  • Very tight parameter tolerances using proprietary IC trimming technology and transformer construction techniques enable Clampless™designs.
  • decreases component count/system cost and increases efficiency.
  • Meets industry standard requirements for thermal overload protection.
  • eliminates the thermal fuse used with linear transformers or additional components in RCC designs.
  • Frequency jittering greatly reduces EMI.
