Fairchild Semiconductor CQ1565RT
The PWM controller includes an integrated fixed frequency oscillator, under voltage lockout, leading edge blanking (LEB), optimized gate driver, internal soft start, temperature-compensated precise current sources for a loop compensation, and self protection circuitry. These devices provide a basic platform that is well suited for cost-effective designs of quasi-resonant switching flyback converters.| Part No. | CQ1565RT |
