LD5523T Datasheet | Leadtrend

04/08/2021 Multi-Mode PWM Controller of Flyback with MOSFET Integrated REV. 00 General Description The LD5523T is built in a multi-mode PWM controller. The multi-mode PWM controller which consists of Quasi-Resonant (QR) PWM control for light load condition and Continue Conduction Mode (CCM) for heavy load condition. Moreover, the QR controller not only gains the system performance, but also brings the worse EMI capability, while the frequency swapping function of LD5523T can reduce the EMI emission of SMPS and helps the power circuit designers to simply deal with EMI filter and saves several ponent and developing time. The LD5523T is implemented in SOT-26 package, and includes...
