ADP3198AJCPZ-RL

Overview

The ADP3198AJCPZ-RL is a synchronous buck controller manufactured by onsemi, designed for high-performance voltage regulation. It features four output channels with an adjustable output voltage range of 500 mV to 1.6 V. The device operates within a temperature range of 0°C to +85°C and utilizes an LFCSP EP surface-mount package. This component belongs to the PMIC category and functions as a switching controller.

Feature Summary

• Synchronous buck control architecture supporting multi-phase configurations
• Integrated internal voltage regulator (VR) functionality
• Supports SYNC BCK control interface for system synchronization

Applications

• High-density server power supplies
• Graphics processing unit (GPU) voltage regulation modules
• Central processing unit (CPU) core power delivery systems

Procurement Notes

Verify current availability status as the component lifecycle is listed as End-of-Life or limited supply. Confirm RoHS compliance details through official datasheets. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement planning.

Selection Notes

Select this controller for applications requiring precise low-voltage regulation with multiple phases. Consider the LFCSP EP package for thermal performance. Validate that the required output voltage range of 500 mV to 1.6 V aligns with target load specifications.

Part Context

This part is part of onsemi's ADP31xx series of switching controllers. It serves as a specialized power management integrated circuit (PMIC) solution. The component is distinct from gate drivers like the ADP3120, focusing instead on complete buck control logic rather than simple MOSFET driving.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, engineering change orders should be initiated to identify qualified alternatives.
