LNK3209GQ-TL is a highly energy efficient switcher IC with integrated system level protection for low component-count power supplies. The LinkSwitch�-TN2 family of IC for automotive power supplies provide significant reduction in component count compared to traditional discrete solutions making it highly reliable. The device family supports buck, buck-boost and flyback converter topologies. This device incorporates a 750V power MOSFET, oscillator, On/Off control, a high-voltage switched current source for self-biasing, frequency jittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown, and output and overvoltage protection circuitry onto a monolithic IC. Applications includes auxiliary power supplies for automotive HVAC, climate control, DC/DC converter and on-board charger, emergency power supply for traction inverter.
