MC34VR500VBES

Power Management - Specialized Overview

The MC34VR500VBES is a multi-output DC/DC regulator from NXP Semiconductors, designed for high-performance power management. It features four buck converters capable of delivering up to 4.5A output current and three user-programmable LDOs. The device operates with an input voltage range of 2.8V to 4.5V and supports a switching frequency of 16MHz. It utilizes a QFN-56 package for surface mount installation and functions within a temperature range of -40°C to +105°C.

Power Management - Specialized Feature Summary

• Integrates four independent buck regulators with high current capability
• Includes three user-programmable low-dropout linear regulators
• Supports I2C interface for register read/write protocol
• Features shutdown control for power management

• LS1 series processors (e.g., LS1023A, LS1043)
• T1 series processors (e.g., T1012, T1023)

Power Management - Specialized Procurement Notes

Verify the specific suffix 'VBES' against official NXP documentation to confirm exact marking and revision status. Ensure compatibility with the target QorIQ or LS/T-series processor power requirements. Confirm humidity sensitivity handling procedures during assembly, as indicated in specifications. Validate that the QFN-56 footprint matches the design layout.

Power Management - Specialized Selection Notes

Select this component when designing for NXP QorIQ or LS/T-series network processors requiring multiple regulated rails. It is suitable for applications needing high-current buck outputs alongside programmable LDOs. Consider the 16MHz switching frequency for EMI constraints and the wide operating temperature range for industrial environments.

Power Management - Specialized Part Context

The MC34VR500VBES belongs to the MC34VR500 series of PMICs specifically engineered for NXP's high-end communication processors. This series provides integrated power solutions for complex SoCs, reducing board space and component count compared to discrete regulator designs.

Power Management - Specialized Replacement Considerations

Check for other suffixes within the MC34VR500 family, such as MC34VR500V9ES or MC34VR500V1ES, which share identical electrical specifications but may differ in packaging or ordering codes.
