Power Tools

Power Integrations offers a broad range of highly integrated, high-voltage ICs for off-line power conversion in power tools applications. Solutions include flyback, two-switch forward, and LLC topologies from 5 to 586 W output power. Each device combines high voltage MOSFETs, a controller, and protection circuitry in the same heat-sinkable package. Accurate constant current (CC) control provides reliable designs that meet the requirements of power tool battery charger applications.

Other features include:

  • Current limiting and thermal shutdown (with automatic fault recovery capability) to improve reliability
  • Frequency jittering to reduce EMI
  • High switching frequency significantly reduces the magnetic size
