LinkSwitch™-TN2 family of ICs for non-isolated off-line power supplies provides dramatically improved performance compared to traditional linear or cap-dropper solutions. Designs using the highly integrated LinkSwitch-TN2 ICs are more flexible and feature increased efficiency, comprehensive system level protection and higher reliability. This family supports buck, buck-boost and flyback converter topologies. Each device incorporates power MOSFET, oscillator, on/off control for highest efficiency at light load, high-voltage switched current source for self-biasing, frequency jittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown, output and input overvoltage protection circuitry onto a monolithic IC. ICs consume very little current in standby resulting in power supply designs that meet all no-load and standby specifications worldwide. Applications includes appliances, metering, smart LED drivers, industrial controls, IOT, home and building automation.
Key Features
- Output current of 120mA (MDCM), 170mA (CCM) at 230VAC and 120mA (MDCM), 170mA (CCM) at 85-265VAC
- Highest performance and design flexibility EcoSmart™ extremely energy efficient
- Enhanced safety and reliability features, auto-restart for short-circuit and open loop faults
- Output overvoltage protection, line input overvoltage and hysteretic overtemperature protection
- Excellent load and line regulation, 66KHz operation with accurate current limit
- Allows use of low-cost off-the-shelf inductors, reduces size and cost of magnetics/output capacitor
- 900V MOSFET rating series for industrial or extra safety margin, pin-out simplifies PCB heat sinking
