ADP2311ACPZ-1-R7 Working Principle

The ADP2311ACPZ-1-R7 is based on a DC-DC switching regulator. This regulator consists of a comparator, an error amplifier, an internal clock oscillator, and a power MOSFET switch. The regulator has an input voltage range of 5V to 24V, and a wide output voltage range of 3.3V to 20V. The regulator is designed to provide 200mA of output current.

The working principle of the device is simple. The comparator compares the differential voltage across the output and the reference voltage, and based on the comparison, it turns the enable input ON or OFF. When the enable input is ON, the power switch connects the input to the output. When the enable input is OFF, the power switch is OFF and the output disconnects from the input. During this process, the error amplifier monitors the voltage and current of the output, and modifies the comparison accordingly, to ensure that the output remains accurate.

The ADP2311ACPZ-1-R7 is a highly efficient device, with a typical efficiency of 87% at a switching frequency of 1.5MHz. It is also RoHS compliant and is available in a SO-16 package.

Overall, the ADP2311ACPZ-1-R7 is a best-in-class DC-DC switching regulator specifically designed for use in automotive electronics. It is suitable for a wide range of automotive applications and offers an adjustable current limit, adjustable preferred voltage input, an internal soft start time, a disable pin, and over-temperature protection.
