CHL8104-02CRT

The CHL8104-02CRT configuration is a DCDC switching controller in a PMIC voltage regulator. CHL8104-02CRT is mainly used in computer power supply modules and buck/boost power modules. Its high switching frequency and high efficiency make it suitable for various super power requirements. It provides regulated current for CPU and memory of coreboard, which can ensure the normal operation of computer.

The working principle of CHL8104-02CRT is divided into two parts: control circuit and output circuit. The control circuit is divided into three parts: Pulse Width Modulation (PWM) oscillator, control logic, and protection control. The PWM oscillator mainly produces a fixed frequency clock signal, and the output signal is connected to the control logic. The control logic has a comparison function and a detector function, which can output the required control signal by comparing the detected voltage signal with the feedback signal.

The CHL8104-02CRT output circuit is mainly composed of an MOSFET drive signal, a power stage MOSFET, an output filter, a rectifier and a signal feedback. The output MOSFET is composed of input MOSFET and output MOSFET, and the output is controlled by driving signal of the input MOSFET. When the input control signal is received, the opening and closing of the input MOSFET is adjusted by the driving signal, and the voltage of the output filter is filtered by the rectifier, and the output signal is fed back to the control logic in order to ensure the accuracy of the voltage output.
