|LinkSwitch™-4 Family ICs - The LinkSwitch-4 family of offline power conversion ICs targets chargers and adapters required to meet stringent new efficiency rules from the US Department of Energy (DoE) and European Code of Conduct (CoC). The new DoE rules, known as DoE-6, require efficiency compliance measurements to be taken at the end of the charger USB cable; LinkSwitch-4 exceeds this requirement while using a low-complexity Schottky diode secondary, even for high-current 1.5 A and 2 A smartphone chargers.
|InnoSwitch™-CH Family of ICs - The InnoSwitch™-CH family of ICs combines primary, secondary, and feedback circuits in a single surface-mounted off-line flyback switcher IC. The InnoSwitch-CH IC incorporates the primary FET, the primary-side controller, and a secondary-side synchronous rectification controller.
|LYTSwitch™-0 LED Driver ICs - Power Integrations' LYTSwitch-0 family is specifically designed for non-isolated, non-dimming LED bulbs and T8 tube applications. LYTSwitch-0 devices integrate a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, high-voltage switched current source, cycle-by-cycle current limit, and thermal shutdown circuitry into a monolithic IC.
|LYTSwitch-4 LED Driver ICs - Power Integrations' LYTSwitch family enables offline LED drivers with high power factor, which easily meet international requirements for THD and harmonics. Tightly-regulated output current, with better than ±5% CC tolerance, enables efficiency of up to 92% in typical applications.
