| Description | Quasi-Resonant PWM Flyback Controller |
|
|
The LD5521 integrate a quasi-resonant PWM control function into a SOT-26 package. It takes less ponents counts or circuit space, especially ideal for those total solutions of low cost. The implemented functions include low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal soft driving.
