It can also be used in applications requiring low power and high accuracy output, such as power management in industrial products, and can be used as part of an A/D converter, such as in industrial applications.

The working principle of LD6806CX4/13H,315 is that, when the output voltage is too low, the positive end of the low-side power MOSFET will be pulled down, which will turn the MOSFET on. Through the current sense amplifier, the voltage difference between the power line and the current sense terminal can be amplified. Based on this, the error signal is generated and sent to the compare circuit, which will reduce the negative side of the high-side power MOSFET (Vgs) until the output voltage is regulated to a stable output.

LD6806CX4/13H,315 is a chip with excellent performance and strong reliability. Its application fields are very wide and it can be applied in the field of battery charger and battery management. Its excellent performance and stable output voltage make it an ideal choice for these applications. In addition, its working principle is simple and easy to understand.
