Working Principle

The NCP1126BP100G is a monolithic chip with an integrated controller, PWM oscillator and MOSFET drivers. The chip is optimized to provide high efficiency, low cost and high reliability. It can generate a regulated voltage from a wide range of AC input voltages, and has a variety of protection functions.

The operation of the chip can be summed up as follows. The chip first converts the AC input voltage to a DC voltage. Then, the onboard controller takes in this DC voltage and generates a time-varying voltage, which serves as the output waveform. This waveform is passed to the PWM oscillator, which determines the operating frequency. Finally, the PWM waveform is passed to the MOSFET drivers, controlling the power conversion efficiency.

In order to maintain stable output voltages, the chip is designed with a variety of protection functions. It has UVLO (under voltage lockout) and runaway protection, as well as overcurrent and overtemperature protection. This ensures the safety and correct operation of the system, even in challenging environments.
