LinkSwitch™ is specifically designed to replace low power linear transformer/RCC chargers and adapters at equal or lower system cost with much higher performance and energy efficiency. LNK500 is a lower cost version of the LNK501 with a wider tolerance output CC characteristic. LinkSwitch introduces a revolutionary patented topology for the design of low power switching power supplies that rivals the simplicity and low cost of linear adapters, and enables a much smaller, lighter, and attractive package when compared with the traditional “brick.”
