Working Principles

The ICE3BR0665JZXKLA1 is a PWM controller designed for offline flyback converters. It operates by regulating the duty cycle of the power MOSFET based on feedback from the FB pin and current sensing through the CS pin. The primary-side regulation eliminates the need for an optocoupler and secondary-side feedback components, simplifying the design and reducing cost.

The controller utilizes frequency jittering to reduce electromagnetic interference (EMI) emissions, ensuring compliance with EMC standards. It also incorporates auto-restart protection, which automatically restarts the converter after a fault condition is removed, enhancing system safety.

Additionally, the ICE3BR0665JZXKLA1 features green mode operation, enabling high efficiency at light load conditions and reducing standby power consumption.
