LD5523D2 - PWM+QR Multi-mode Controller
In order to enhance the efficiency performance, the LD5523D2 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 gains the system performance, but
