LD5523K Datasheet | Leadtrend

04/23/2019 Multi-Mode PWM Controller of Flyback with REV. 01 Integrated BNI/BNO and Bulk cap. OVP General Description In order to enhance the efficiency performance, the LD5523K integrates 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 LD5523K 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 LD5523K is...
