Working Principle

The CS5124XD8G is an intelligent switching controller that provides the user with complete control over the output voltage. The device converts the input voltage to a fixed output voltage based on an onboard microcontroller and logic circuit. The device also includes a current limit and over voltage protection circuit.

In order to ensure efficient operation, the CS5124XD8G uses a single-phase voltage feedback loop with a pulse width modulation (PWM) technique to control the output voltage. The PWM input from the microcontroller is integrated with the voltage feedback loop to enable precise control over the output voltage.

The device also features an on-chip EEPROM that enables users to store and recall the settings of the controller. This allows for easy and quick reconfiguration depending on the application requirements. The onboard microcontroller also supports user-programmable settings for power saving modes such as Burst Mode operation, as well as soft start and active stop modes.

Lastly, the CS5124XD8G features an additional single-wire programming feature to enable remote control and configuration by the user. This feature allows for easy integration of the device into OEM designs and power management applications.

Conclusion

The CS5124XD8G is an ideal dc-dc switching controller for battery charging, motor control, and power management applications. It offers an intelligent control feature set with very low power consumption and an onboard microcontroller capability and EEPROM, enabling user-programmable settings for power saving modes such as Burst Mode operation. The single-wire programming feature also allows for easy integration into OEM designs.
