LinkSwitch Family

LinkSwitch Family products incorporate a high-voltage power MOSFET, oscillator, simple ON/OFF control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC. The startup and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry.

EcoSmart® technology enables designs to easily meet current no-load consumption efficiency standards set forth by the California Energy Commission (CEC), US Government, and other regulatory agencies.

Typical applications include:

  • Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio players, and shavers
  • Supplies for appliances, industrial systems, and metering

LinkSwitch-CV - The LinkSwitch-CV dramatically simplifies CV power supply design with tight CV requirements and by eliminating an optocoupler and secondary control circuitry. The device introduces a revolutionary control technique to provide very tight output voltage regulation, along with input voltage variations and temperature.

LinkSwitch-II - Designed for low power adapters and chargers (cell/cordless phones, PDAs, digital cameras, portable audio etc), LinkSwitch-II dramatically simplifies low power CV/CC charger designs by eliminating an optocoupler and secondary control circuitry. The device introduces a revolutionary control technique to provide very tight output voltage and current regulation, compensating for transformer and internal parameter tolerances along with input voltage variations.

LinkSwitch-XT - Designed for low power adapters and chargers (cell/cordless phones, PDAs, digital cameras, portable audio etc), as well as auxiliary supplies employed in applications such as white goods

LinkSwitch-LP - Designed to replace inefficient line frequency linear transformer based power supplies with output powers < 2.5 W in applications such as cell/cordless phones, PDAs, digital cameras, and portable audio players, as well as auxiliary supplies employed in applications such as white goods.

LinkSwitch-TN - Designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency.
