Working Principle of the ISL6565ACBZ
The working principle of the ISL6565ACBZ is based on the active voltage regulation technology. This means that the output voltage is sensed by the device and compared against an internal reference voltage.The voltage sensing is done by the device\'s internal sense pin, which is connected to the output of the regulated power supply. The internal reference voltage is set via a resistor divider on the input of the device. When the voltage is higher than the reference voltage, the device will reduce the PWM duty cycle to decrease the amount of power supplied to the load. When the voltage is lower than the reference voltage, the device will increase the duty cycle to increase the amount of power supplied to the load. This will ensure that the output voltage remains within a set range and is regulated.Conclusion
The ISL6565ACBZ is a monolithic integrated circuit, which is an active Pulse-Width Modulation (PWM) step-down DC-DC controller manufactured by Renesas. It is designed to provide a broad analog voltage regulation solution for applications such as point-of-load (POL) voltage regulation, power factor correction (PFC), direct current to direct current (DC-DC) conversion, applications that require high levels of accuracy, and low noise voltage source from a single source. It offers a wide range of features to enable it to be deployed in a variety of applications and can be used in a number of applications such as point-of-load (POL) convertors, automotive power inverters and power supplies.The working principle of the ISL6565ACBZ is based on Active Voltage Regulation Technology which helps to regulate the output voltage in a range required. It senses the output voltage and compares it against an internal reference voltage, and adjusts the PWM duty cycle as to increase or decrease the power supplied to ensure the desired output voltage is achieved. This makes the ISL6565ACBZ an ideal solution for applications that require precise control of the output voltage.The specific data is subject to PDF, and the above content is for reference
