LD5523 - Multi-Mode PWM Controller

Description

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.

Features

  • Secondary-side feedback control with quasi-resonant + CCM operation.
  • Low Startup Current (.

LD5523/R/H/E 10/14/2016 Multi-Mode PWM Controller of Flyback with Integrated BNI/BNO and Protection REV. 00 General Description 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 component and developing time.
