LinkSwitch™ is specifically designed to replace low powerlinear transformer/RCC chargers and adapters at equal orlower system cost with much higher performance and energyefficiency. LNK500 is a lower cost version of the LNK501 with awider tolerance output CC characteristic. LinkSwitch introducesa revolutionary patented topology for the design of low powerswitching power supplies that rivals the simplicity and lowcost of linear adapters, and enables a much smaller, lighter,and attractive package when compared with the traditional“brick.” With efficiency of up to 75% and <300 mW no-load consumption, a LinkSwitch solution can save the end userenough energy over a linear design to completely pay forthe full power supply cost in less than one year. LinkSwitchintegrates a 700 V power MOSFET, PWM control, high voltagestart-up, current limit, and thermal shutdown circuitry, onto amonolithic IC.
