精密DAC和看门狗提高模拟输出安全
Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and data-acquisition systems. The analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failu ...

DN1011 简单高效率隔离型反激式电源
 
While simplicity and high effi ciency (for cool running) areno longer optional features in isolated power supplies, itis traditionally diffi cult to achieve both. Achieving higheffi ciency often requires the use of advanced topologiesand home-brewed secondary synchrono ...
