LinkSwitch-4 Series AC / DC Off Line Converters:

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.

• Eliminates optocoupler and all secondary CV/CC control circuitry
• Meets DoE 6 and CoC V5 2016 via an optimized quasi-resonant switching PWM/PFM control
• Dramatically reduces sensitivity to BJT gain
• No-load consumption of <30 mW="" at="" 230="" VAC="" input<=""/>
• Easy start for starting into capacitive loads
• Constant power for high current start-up
• Single fault output overvoltage and short-circuit Protection
• Over-temperature protection
• Halogen Free and RoHS Compliant package
• Applications: Chargers for cell/cordless phones, PDAs, MP3/portable audio devices, networking
