Fairchild Semiconductor’s new FL7701 is a non-isolated buck LED driver with power factor correction (PFC). It uses a digital technique that allows it to automatically detect the AC input voltage condition, allowing it to create a special internal reference signal that results in high PFC. It will also work from a DC input voltage condition, automatically sensing AC versus DC input voltage conditions. Available in an SOP-8 package, the FL7701 is suitable for interior decorating/ornamental lights; LED light bulbs or down lights in PAR, reflector, MR or classic styles E26/E27 or Bi-Pin base, as well as LED lamps for low-power lighting fixtures.
