ADP3191JRUZ-RL

Special Purpose Regulators Overview

The ADP3191JRUZ-RL is a 6-bit programmable synchronous buck switching regulator controller from Analog Devices Inc. It supports selectable 2-, 3-, or 4-phase operation with frequencies up to 1 MHz per phase. Designed for Intel VRM applications, it converts 5 V or 12 V main supplies into lower voltage rails. The device features a worst-case differential sensing error of ±14.5 mV over temperature and operates within a specified ambient temperature range.

Special Purpose Regulators Procurement Notes

Verify the exact suffix JRUZ-RL against the manufacturer datasheet to confirm package type and reel quantity specifications. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement orders.

Special Purpose Regulators Selection Notes

Select this component when designing multiphase converters requiring programmable phase counts and high accuracy. Consider the ±14.5 mV sensing error tolerance and input voltage range suitability for your specific load transient requirements.

Special Purpose Regulators Part Context

This part belongs to the ADP319x series of special purpose regulators. It shares architectural similarities with the ADP3190 but offers enhanced programmability through its 6-bit interface. The series is optimized for converting standard bus voltages into processor core supplies.

Special Purpose Regulators Replacement Considerations

The ADP3190JRQZ-RL is a related controller in the same family. Verify if the fixed-phase configuration of the ADP3190 meets your design needs as an alternative.
