CR6842
The CR6842 is less than 100W off-line switching power supply IC, the IC drive circuit and current mode PWM controller optimized totem. PWM controller contains the frequency of oscillation generator as well as a variety of protection. Frequency jitter generated by the oscillator circuit can be improved EMI characteristics. In order to obtain good efficiency and standby power consumption, CR6842 in overloaded or medium load, working in PWM mode. When the load is gradually reduced, the operating frequency of the oscillator is gradually reduced, and finally stabilized at around 10KHz. In the no-load and light load, the circuit green mode reduces standby power consumption efficiency. Protection features include: undervoltage lockout, overload protection, over-temperature protection, over-voltage protection and clamp, protection can be automatically lifted after restoration work.
The CR6842 highly integrated, the use of small external components. Using CR6842 can simplify the flyback isolated AC-DC switching power supply design, enabling designers to easily access reliable system.
