TNY275GN-TL – Power Integrations TinySwitch-III Energy-Efficient Offline Flyback Switcher IC

Quick Answer The TNY275GN-TL is a highly integrated offline flyback switcher IC from Power Integrations' TinySwitch-III family. It combines a 700V power MOSFET with an on-chip controller in a compact SMD-8C package. Capable of delivering up to 15W (open frame, 230 VAC) / 11W (universal input open frame), it offers excellent efficiency, user-selectable current limit, frequency jitter for low EMI, and very low no-load consumption. Ideal for medium-power isolated AC-DC adapters, chargers, and LED drivers.
