NCP5332ADWR2

Overview

The NCP5332ADWR2 is a high-performance dual-output voltage regulator controller manufactured by onsemi. Designed for processor power applications, it operates within an input voltage range of 4.5V to 14V and provides two adjustable outputs. The device is housed in a 28-SOIC package with a width of 7.50mm. It supports surface-mount installation and functions within a commercial temperature range of 0°C to 70°C. This component serves as a specialized power management integrated circuit (PMIC) intended for complex digital loads requiring precise multi-rail regulation.

Feature Summary

• Dual-output control architecture optimized for high-performance processor power sequencing
• Adjustable output voltage capability for flexible system design integration
• Wide input voltage operating range supporting various bus architectures

Applications

• High-performance processor voltage regulation
• Multi-rail power supply systems
• Complex digital load power management

Procurement Notes

Verify the specific ordering suffix 'R2' against current manufacturer documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as historical data indicates potential non-compliance for earlier variants. Check availability through authorized distributors or third-party suppliers due to discontinuation status. Ensure the 28-SOIC footprint matches the target PCB layout requirements before procurement.

Selection Notes

Select this controller when designing power stages for processors requiring two distinct regulated rails. Evaluate the 4.5V to 14V input constraint against the system's available power source. Consider the 28-SOIC thermal performance and board space constraints. Verify that the adjustable output range meets the core voltage requirements of the target processor. Compare against newer generations if long-term supply assurance is critical.

Part Context

This component belongs to onsemi's Special Purpose Voltage Regulators category within their Power Management IC portfolio. It is part of the NCP5332 family, which focuses on advanced control solutions for demanding digital applications. The device complements other PMIC offerings by providing dedicated dual-channel control rather than single-output or multi-phase integrated drivers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The product listing indicates the item is discontinued. Users should consult onsemi technical support or authorized distributor catalogs for direct replacements or next-generation equivalents suitable for processor power applications.
