PSR ACDC-CN1811

CN1811 uses primary-side voltage and current sampling technology, eliminating the need for optocouplers and secondary-side control circuits, simplifying CV/CC mode switching power supply design. It also has precise output voltage and current regulation. CN1811's multiple operating modes can achieve 75mW of standby power consumption, high efficiency and no noise. Frequency jitter technology can greatly reduce the cost of EMI filters. CN1811 in DIP-7 package can accurately adjust CV/CC, with low cost and high reliability. At the same time, it provides a wealth of protection functions: including cycle-by-cycle peak current limiting, VCC undervoltage lockout (UVLO), overvoltage protection (OVP) and clamping. When an abnormality occurs, the controller continues to try soft restart until the fault condition is eliminated.
