NCP5332ADW

Overview

The NCP5332ADW is a high-performance two-phase buck controller manufactured by onsemi, designed for powering advanced processors. It operates within an input voltage range of 4.5V to 14V and features adjustable output voltage control. The device integrates gate drivers and a five-bit digital-to-analog converter (DAC) for precise regulation. Packaged in a 28-SOIC format, it supports surface-mount installation and functions reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrates dual-channel gate drivers for synchronous buck topology operation
• Includes a five-bit DAC for programmable voltage adjustment
• Supports two-phase architecture for high-current processor power delivery

Applications

• High-performance processor power supplies
• Two-phase DC-DC conversion systems
• Advanced FPGA and ASIC core voltage regulation

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt. Ensure supply chain sources provide traceability documentation. Check for alternative sourcing options if original manufacturing lines are unavailable.

Selection Notes

Select this controller for applications requiring integrated gate driving capabilities without external driver components. The built-in DAC allows for simplified voltage programming compared to resistor-divider configurations. Consider the 28-SOIC footprint for PCB layout constraints. Evaluate thermal management needs based on the specified operating temperature range and load conditions.

Part Context

This component belongs to the NCP5332 family of power management ICs from onsemi. It serves as a specialized controller for multi-phase buck converters. The ADW suffix indicates the specific tape-and-reel or tube packaging variant within the standard product line. It complements other PMIC solutions by providing dedicated control logic for high-density power stages.
