LD5523K

Multi-Mode PWM Controller of Flyback with Integrated BNI/BNO and Bulk cap. OVP

In order to enhance the efficiency performance, the LD5523K 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 performa; • Secondary-side feedback control with quasi-resonant + CCM operation\n• Low Startup Current (<1μA)\n• 0.285mA Ultra-low operating current at light load \n• Current Mode Control with Cycle-by-Cycle Current Limit\n• Green Mode Control\n• UVLO (Under Voltage Lockout)\n• LEB (Leading-Edge Blanking) on ;
