LinkSwitch�-TNZ family of ICs combine power conversion with lossless generation of AC zero crossing signal used typically for system clock and timing functions. Designs using the highly integrated LinkSwitch-TNZ ICs are more flexible than discrete implementations reducing component count by 40% or higher. Besides enabling 80+ efficiencies in low power flyback designs, very low consumption at light loads enabled by On/Off control allow for more functions (display, wireless connectivity, sensors etc.) to be active during system standby. The device family supports buck, buck-boost and flyback converter topologies. Each device incorporates a 725 V power MOSFET, oscillator, a high-voltage switched current source for self-biasing, frequency jittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown and output and input overvoltage protection circuitry onto a monolithic IC.
- Enables ±3% regulation across line and load
- Selectable device current limit
- 66KHz operation with accurate current limit
- Frequency jittering reduces EMI filter complexity
- Soft-start limits system component stress at start-up
- Auto-restart for short-circuit and open loop faults
- Extended creepage between DRAIN pin and all other pins improves field reliability
- Nemko (EN62368-1) and CB (IEC62368-1) certifications
- IC standby supply current <100 mA, No-load consumption <30 mW with external bias
- On/Off control provides constant efficiency over a wide load range
