Power Integrations, Link Switch 63 A, 80 A 8-Pin, SO-8C LNK3312D-TL

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
