Descriptions:

The ADP3192J is a high-efficiency, multi-phase synchronous buck PWM controller designed for high-current, low-voltage applications such as powering CPUs and GPUs. It provides precise voltage regulation with adaptive voltage positioning (AVP) and supports dynamic phase management for improved efficiency across load ranges.

Features:

• Precision Voltage Regulation: ±0.5% system accuracy over temperature
• Adaptive Voltage Positioning (AVP): Reduces output capacitance requirements
• Dynamic Phase Management: Automatically adjusts the number of active phases for optimal efficiency
• Programmable Soft-Start: Prevents inrush current
• Overcurrent Protection (OCP): Uses inductor DCR or sense resistor for accurate current monitoring
• Overvoltage Protection (OVP) and Undervoltage Lockout (UVLO): Ensures safe operation
• Differential Remote Sensing: Compensates for PCB trace resistance
• Power-Good Output: Monitors output voltage status
