PSR ACDC-CN1611

Adopting the primary side voltage and current sampling technology, CN1611 simplify the CV/CC mode switching power supply design without optical coupling and secondary side control circuit, but also has accurate output voltage and current regulation. CN1611 can realize 75mW standby power consumption, high efficiency and no noise in multiple operation modes. Frequency jitter technology can greatly reduce the cost of EMI filter. The CN1611 of DIP-7 package can be adjusted accurately CV/CC, which has the advantages of low cost and high reliability. At the same time, it provides rich protection functions: It includes cycle by cycle peak current limitation, VCC under voltage locking (UVLO), over voltage protection (OVP) and clamping. When fault occurs, the controller still try soft restart until the fault condition is eliminated. CN1611 provides DIP-7 package, with built-in MOSFET with withstanding voltage up to 1000V, to ensure reliable operation of the product in harsh power supply environment.
