Device identity and function
The ADP3191AJRUZ-RL is a 6-bit, programmable 2-/3-/4-phase controller from Analog Devices, designed for Intel VRM applications. It integrates the control logic for multi-phase buck converters, allowing the output voltage to be set digitally via a 6-bit VID code. The part accepts a 5V or 12V input rail and delivers a regulated output from 0.84V to 1.6V, with four output phases supporting high-current processor rails.
Housed in a 28-TSSOP (0.173", 4.40mm width) surface-mount package, the ADP3191AJRUZ-RL fits standard reflow profiles. The supplier device package is 28-TSSOP, with a 0.65mm lead pitch typical for this body size. The operating temperature range is 0°C to 85°C, suitable for commercial and enterprise computing environments.
Sourcing and cross-reference
The ADP3191AJRUZ-RL is available to order through independent distribution. For BOM flexibility, peer parts ADP3191AJRQZ-RL, ADP3191JRUZ-RL, and ADP3191JRQZ-RL share the same 4-output, 5V/12V input, 0.84V-1.6V output specification and 28-pin TSSOP footprint — the suffix differences reflect packaging or lead-free options.
