Power Integrations, Link Switch 120 A, 170 A 8-Pin, SO-8C LNK3304D-TL / 2286361

The Power Integration LinkSwitch-TNZ series of ICs combine power conversion with lossless generation of AC zero crossing signal used typically for system clock and timing functions. Each device incorporates a 725 V power MOSFET, oscillator, a high-voltage switched current source for self-biasing, frequency jittering, fast current limit, hysteretic thermal shutdown, and output and input overvoltage protection circuitry onto a monolithic IC.Lossless zero cross signal generation Supports buck, buck-boost and flyback topologies Frequency jittering reduces EMI filter complexity Soft-start limits system component stress at start-up Hysteretic over-temperature protection
