LD5523T 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...
