Smart Lighting

Power Integrations offers a range of integrated high-voltage ICs to power Smart Lighting applications. These ICs work with various communication protocols from wireless and wired PWM to wired DALI connectivity. These solutions incorporate power FET, control and protection circuitries on a single chip, enabling customers to design low component count solutions with fast time to market. Efficiency regulators continue to mandate very low standby power. Power Integrations ICs provides the lowest standby power for smart lighting in the market today.

Features include:

  • The flyback solution offers CV/CC or CC capability with high accuracy, enabling multiple output channels without the need of an additional DC/DC converter.
  • The buck solution offers a simple, low component solution for auxiliary or standby power supplies to power the microcontroller and the radio wireless module.
