The LinkSwitch-II family of devices were developed to cost effectively replace all existing solutions in low-power charger and adapter applications. Its core controller is optimized for CV/CC charging applications with minimal external parts count and very tight control of both the output voltage and current, without the use of an optocoupler. The LinkSwitch-II device has an integrated 700 V switching MOSFET and ON/OFF control function which together deliver high efficiency under all load conditions and low no-load energy consumption. Both the operating efficiency and no-load performance exceed allcurrent international energy efficiency standards.


  •  Control concept provides very low cost, low part-count solution Primary-side control eliminates secondary-side control and optocoupler Provides ±5% constant voltage (CV) and ±10% constant current (CC) accuracy includingoutput cable drop compensation Over-temperature protection – tight tolerance (±5%) with hysteretic recovery for safe PCBtemperatures under all conditions Auto-restart output short circuit and open-loop protection Extended pin creepage distance for reliable operation in humid environments; >3.2 mm atpackage EcoSmartTM – Easily meets all current international energy efficiency standards – China(CECP) / CEC / ENERGY STAR 2 / EU CoC No-load consumption <150 mw at 230 vac Ultra-low leakage current: <5 A at 265 VAC input (no Y capacitor required) Design easily passes EN550022 and CISPR-22 Class B EMI testing with >8 dB margin
