ADP3191JRQZ-RL Description

ADP3191JRQZ-RL 6-bit, programmable 2-/3-/4-phase, synchronous buck switching regulator controller provided by ON Semiconductor. It is specifically designed to convert a 5 V or 12 V main supply into the core supply voltage for high-performance Intel processors. A voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.8375 V and 1.6 V, can be read by the internal 6-bit DAC.  It is available in a 28-lead TSSOP and a 28-lead QSOP for saving board space.

ADP3191JRQZ-RL Features

Selectable 2-, 3-, or 4-phase operation at up to 1 MHz per phase

Logic-level PWM outputs

Active current balancing between all output phases

Built-in power good/crowbar blanking

Accurate and reliable short-circuit protection
