04/12/2021
Multi-Mode PWM Controller of Flyback with
Frequency Swapping and Integrated Protection
REV.00
General Description
In order to enhance the efficiency performance, the LD5523M1 integrates the multi-mode PWM controller, which consists of Quasi-Resonant (QR) PWM control for light load condition and peak load mode 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 LD5523M1 can reduce the EMI emission of SMPS and helps the power circuit designers to simply deal with EMI filter and saves several component and developing time.
