In order to enhance the efficiency performance, the LD5523/R/H/E 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 LD5523/R/H/E 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 LD5523/R/H/E is implemented in SOT-26 package, and includes the prehensive protection function, such as Over Load Protection (OLP), Over Voltage Protection (OVP), Output Short Circuit Protection (OSCP) and internal Over Temperature Protection (OTP).
