FAN5701UC20X Working Principle
The FAN5701UC20X is a highly efficient and high performance, ultra-low standby current, power factor correction (PFC) integrated circuit. It adopts peak current mode control and includes a PFC pre-regulator, main control chip and an optimized drive circuit. The basic working principle is as follows:
When the input voltage reaches a certain level, the PFC pre-regulator generates a detection signal and the power switch is turned on. The chip will generate a required period of PWM pulses to make the switch in the on state. At the same time, it will accumulate energy to the voltage output of the detected voltage according to integration method and form a continuous pulse. The pulse is then sent to PWM processing and corresponding dimming is achieved by adjusting the dimmer. The same principle applies to control of output current.
When the power switch is in the on state and the voltage output reaches the detection voltage value, the PFC pre-regulator will enter the off state, and the constant frequency of the PWM will stop the switch from working. After the power switch is reset, the PWM process will start again, and the power switch will be turned on again.
To ensure normal operation of the FAN5701UC20X, the chip has provided designers with a variety of protection and alarm functions. These include protection mode such as overvoltage protection, overcurrent protection and short circuit protection, among others. In case of abnormal operation of the device, the system will generate an alarm signal to trigger an emergency shutdown process.
Conclusion
The FAN5701UC20X is a PMIC - LED Drivers, suitable for LED driver applications in user terminal equipment, AC adapters, power amplifiers and LED drivers in a wide variety of applications, with built-in power management and protection functions. It offers wide interconnection with wideband support, an optimized drive circuit for improved dynamic response and power efficiency, and protective functions for data integrity. These make the integrated circuit an excellent product for LED lighting applications.
