Features

The CS51414ED8G provides the following features:

• 2.75V to 5.5V input voltage range
• High efficiency with maximum duty-cycle of 99%
• High level of integration for simple configuration and reduced component count
• Very low standby power consumption
• Synchronous switch mode operation for improved efficiency and low noise.
• Over-temperature, short-circuit and over-current protection.

Working Principle

The CS51414ED8G is a synchronous step-down converter, meaning it converts a higher input voltage to a lower output voltage. This is achieved by using a Pulse-Width Modulated (PWM) signal, which adjusts the duty cycle of a gate signal. This gate signal then switches the power to the output, allowing the output voltage to be regulated. As the output voltage changes, the duty cycle of the gate signal is adjusted. This PWM signal is generated internally using an error amplifier and a voltage reference.

The CS51414ED8G is also capable of providing a constant output voltage, regardless of fluctuations in the input voltage. This is achieved by using a feedback loop, which allows the device to monitor the output voltage and adjust the duty cycle accordingly. Furthermore, the CS51414ED8G is designed to provide high efficiency, with a maximum duty cycle of 99%. This reduces power loss and improves the overall performance of the device.

Conclusion

The CS51414ED8G is a robust and highly efficient DC/DC synchronous step-down converter, which is suitable for industrial and automotive applications. It offers a high level of integration and a very low standby power consumption, making it ideal for battery-powered vehicles. In addition, it features a wide input voltage range, high efficiency, and over-temperature, short-circuit and over-current protection. Finally, it utilizes a pulse-width modulated signal and a feedback loop to ensure a constant output voltage, regardless of fluctuations in the input voltage.
