PMIC-Voltage Regulators- DC DC Switching Regulators

The ADP5301ACBZ-1-R7 integrated circuit is a step-down switching regulator with monitoring capabilities that was developed by Analog Devices for power conversion applications. It is part of the company\'s Power by Linear microPMIC family of products, which are optimised for extremely low-power application-specific microprocessors and multitasking devices. The ADP5301ACBZ-1-R7 switching regulator is designed to offer high system efficiency, allow flexibility in powering a wide variety of application-specific microprocessors in a small form factor, and provide superior EMI/EMC performance.

Application Field

The ADP5301ACBZ-1-R7 switching regulator is ideal for powering processor power sub-systems such as core voltage and I/O logic. This device is suitable for applications that require high performance, low noise, and low quiescent current. It is well suited for use in automotive, consumer electronics, communications, networking, industrial, and medical products.

The ADP5301ACBZ-1-R7 can be used in low standby current systems, providing an ultra-low ideal diode controller that reduces the quiescent current of the system. The ADP5301ACBZ-1-R7 regulator also provides an adjustable soft-start feature that limits inrush current and maximizes system stability. Additionally, the device can be used in applications where fast transient response and tight regulation are required.

Working Principle

The ADP5301ACBZ-1-R7 switching regulator works by controlling a switching element (such as a FET) to smoothly convert input voltage to a regulated output voltage. This regulated output voltage is then sent to the Load (processors, I/O logic, etc.). The regulation loop of the ADP5301ACBZ-1-R7 uses an internal control signal from the Regulation Sense (FB) pin to compare the output voltage to a reference voltage and to adjust the PWM duty cycle, thus controlling the output voltage.

The ADP5301ACBZ-1-R7 offers two different control modes - voltage mode or current mode. In voltage mode, the output voltage is regulated by controlling the voltage at the Feedback pin. In current mode, the output current is regulated by controlling the current at the Current Sense pin. The control mode is selected by the control pin (FC).

The ADP5301ACBZ-1-R7 also provides several other features, such as adjustable soft start, enable/disable, overtemperature protection, short-circuit protection, and undervoltage lockout.

The ADP5301ACBZ-1-R7 integrated switch-mode regulator is a highly efficient, low noise, and low quiescent current solution for advanced, power-sensitive applications.
