LNK563D Energy Efficient Off-Line Switcher

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. The self-biased circuit achieves an extremely low no-load consumption of under 150 mW. The internal.

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
  – enables low cost input filter configuration
• Meets HV creepage requirements between DRAIN and all other pins, both on the PCB and at the package
• P.
