L6562DTR

L6562DTR is a transition-mode current-mode power factor correction controller from STMicroelectronics in an SOIC-8 package, supplied on tape and reel. It operates from a 10.3 to 22V supply and starts up drawing no more than 70 microamps, which helps offline front ends meet tight standby and start-up budgets while shaping the input current of boost PFC pre-regulators in adapters, lighting supplies and appliance power stages. A proven controller of this type lets design teams build a compliant PFC stage with a well-understood control scheme and a small external component set. Status note: STMicroelectronics lists L6562DTR as NRND, not recommended for new designs, and this page keeps that status visible rather than presenting the part as a current mainstream choice; it remains relevant for production support, spares and maintenance of the many designs already built around the L6562. Selection and sourcing advice: if you are servicing or continuing an existing L6562 design, quote the full L6562DTR code so the SOIC-8 tape-and-reel version is supplied; if you are starting a new PFC design, treat the wider L6562 and L6563 family in ST documentation as the starting point for the new platform and re-validate efficiency and EMC, rather than dropping this NRND controller into a fresh design.
