ADP1864AUJZ-R7 is a mid-range, low-power 6A synchronous buck regulator with integrated power-FETs. It is a highly configurable, high-efficiency DC-DC solution that is ideal for space-constrained installations. It features a wide input voltage range of 2.5V to 5.5V, adjustable output current limit, programmable switching frequency up to 1MHz, and overcurrent protection.

ADP1864AUJZ-R7 is a PMIC (Power Management IC) used for voltage regulation and DC-DC conversion. It belongs to the family of DC-DC Switching Controllers which can regulate the output voltage of a power supply by switching a FET (Field Effect Transistor) on and off at a precise rate. The feedback circuit for the DC-DC Switching Controller is used to monitor the output voltage and alter the switching frequency to adjust the output voltage accordingly.

The ADP1864AUJZ-R7 has an integrated 120A high-side power FET and 30A low-side FET, making it well suited for step-down applications operating up to 2A. It has an adjustable operating current limit of 0-600mA, allowing users to set the output current to match their system requirements. The output voltage can be adjusted by adjusting the duty cycle of the switching FETs, delivering an output voltage range of 0.8V to 5V.

It is designed with a power supply good block to ensure that the power is good before any of the accessories are used. This allows the user to monitor the input power and enables the power supply to be shut down quickly in the event of a power supply problem. It also features over current protection, soft-start and programmable switching frequency, allowing it to be easily configured to meet a wide range of requirements.

The ADP1864AUJZ-R7 is ideally suited for a wide range of applications such as computing, consumer electronics, automotive, industrial and lighting. It is well suited for space-constrained installations and supports a wide operating temperature range of -40 to +125℃.

In conclusion, the ADP1864AUJZ-R7 is a high-efficiency DC-DC Switching Controller with adjustable output current limit and programmable switching frequency up to 1MHz. It is ideal for space-constrained installations and can be used for a wide range of applications including computing, consumer electronics, automotive, industrial and lighting. It offers a wide input voltage range of 2.5V to 5.5V and adjustable output voltage range of 0.8V to 5V, making it a highly configurable and advantageous DC-DC solution.
