Power Management Integrated Circuit (PMIC) are a type of integrated circuit (IC) used to manage the power of an electronic device. PMICs often come in the form of voltage regulators, which regulate the voltage of an electronic device. One type of voltage regulator is a DC DC switching regulator. The ADM660ARUZ is a DC DC switching regulator from Analog Devices, Inc.

The ADM660ARUZ is specifically designed for hot-swap board-level power supply systems. By switching between two consecutive input voltages, the IC allows the user to supply power to a device without the need to turn the power off and on. This makes the IC suitable for applications where quick power supply is necessary, such as in telecommunications, automotive and industrial electronics.

In its simplest form, the ADM660ARUZ consists of a P-channel MOSFET and a control logic circuit. The P-channel MOSFET acts as a switch that completes the circuit when the input voltage is within a predetermined range. When the input voltage exceeds the predetermined range, the logic circuit compares the input voltage to a reference voltage and makes a decision whether to turn the P-channel MOSFET on/off. The switching of the MOSFET creates the output voltage, which is then regulated by a control circuit.

The ADM660ARUZ is a four-terminal (IN, GND, OUT, GND) device. It has two primary operating modes: under-voltage lockout (UVLO) and load based current regulation (LBCR). In UVLO mode, the device monitors the input voltage and shuts off when the voltage falls below a certain level. In LBCR mode, the device will regulate the output voltage to a predetermined level depending on the load. This allows the device to respond to changes in the load quickly and efficiently.

The ADM660ARUZ has a wide operating temperature range of -40 to 125 degrees C and is available in a 28-pin, surface-mountable package. The IC has a wide input voltage range of 4 V to 18 V and an output voltage range of 3 V to 10 V. It has a quiescent current of 0.75 mA, a power dissipation of approximately 1 W, and a maximum output current of 3 A. The device is also capable of frequency synchronization, allowing it to be used in multiple power systems.

Overall, the ADM660ARUZ is a relatively easy-to-use IC, and its features make it suitable for hot-swap board-level power supplies. Its wide temperature range and synchronizable frequency makes it an excellent choice for applications that require quick responses and power flexibility. With its user-friendly design and wide range of features, the ADM660ARUZ is a versatile, reliable, and cost-effective DC DC switching regulator for a variety of applications.
