The document introduces the features and characteristics of the ADP3163, a 5-bit programmable 2-/3-phase synchronous buck controller. It features ADOPT™ Optimal Positioning Technology for superior load transient response and fewest output capacitors. It complies with VRM 9.0 and Intel VR Down guidelines with the lowest system cost. It supports digitally selectable 2- or 3-phase operation at up to 500 kHz per phase. It provides quad logic-level PWM outputs for interface to external high-power drivers. It enables active current balancing between all output phases and accurate multiple VRM module current sharing. It has a 5-bit digitally programmable 1.1 V to 1.85 V output and a total output accuracy of ±0.8% over temperature. It operates in current-mode and includes short circuit protection and enhanced power good output to detect open outputs in multi-VRM power systems. It also has overvoltage protection.
