The Power Integrations LNK409LG is a LinkSwitch®-PH series AC/DC offline switcher IC designed for LED driver applications. This flyback topology device features an integrated switch capable of handling up to 725V supply voltage. Optimized for triac dimming, it delivers 3.26A output current from a single channel. The LNK409LG operates at a 66kHz switching frequency, facilitating compact transformer designs and efficient power conversion. Its eSIP-7F package, a 7-lead SSIP with an exposed pad and formed leads, is suitable for through-hole mounting. This component is widely utilized in solid-state lighting solutions where precise dimming and high energy efficiency are critical. The operating temperature range is -40°C to 150°C (TJ).
