      The L6565 is a current-mode primary controller IC, specifically designed to build offline Quasi-resonant ZVS (Zero Voltage Switching at switch turn-on) flyback converters.<\/p>\n

      Quasi-resonant operation is achieved by means of a transformer demagnetization sensing input that triggers MOSFET’s turn-on.<\/p>\n

      Converter’s power capability variations with the mains voltage are compensated by line voltage feedforward. At light load the device features a special function that automatically lowers the operating frequency still maintaining the operation as close to ZVS as possible. In addition to very low start-up and quiescent currents, this feature helps keep low the consumption from the mains at light load and be Blue Angel and Energy Star compliant.<\/p>\n

      The IC includes also a disable function, an on-chip filter on current sense, an error amplifier with a precise reference voltage for primary regulation and an effective two-level overcurrent protection.<\/p>\n","protected":false},"featured_media":1590,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[42],"product_tag":[],"class_list":{"0":"post-1335","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-stmicroelectronics","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"yoast_head":"\nL6565ST SOIC - SMD Electro<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/smdelectro.com\/index.php\/product\/l6565st-soic\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"L6565ST SOIC - SMD Electro\" \/>\n<meta property=\"og:description\" content=\"The L6565 is a current-mode primary controller IC, specifically designed to build offline Quasi-resonant ZVS (Zero Voltage Switching at switch turn-on) flyback converters.
