MC34VR500V2ESR2

Power Management - Specialized Overview

The MC34VR500V2ESR2 is a quad buck switching voltage regulator from NXP Semiconductors, housed in a QFN-56 package. It features four independent DC/DC channels with adjustable outputs and up to 4.5 A output current per channel. The device operates within an input voltage range of 2.8 V to 4.5 V and supports a switching frequency of 16 MHz. Factory-programmed LDOs are integrated alongside the buck converters. The component exhibits a load regulation of 0.4 mV/mA and functions reliably across an operating temperature range of -40°C to +105°C.

Power Management - Specialized Feature Summary

• Integrates four independent high-current buck converters with factory-programmed LDOs for comprehensive power management.
• Supports high-frequency operation at 16 MHz to optimize external component size and transient response.
• Provides precise voltage regulation with low load regulation characteristics for stable system performance.

Power Management - Specialized Applications

• Powering network processor systems such as LS1023A and T1012
• Supplying industrial building automation controllers
• Powering mobile computer platforms

Power Management - Specialized Procurement Notes

Verify the specific suffix 'ESR2' indicates reel packaging when ordering. Confirm compatibility with target network processors like LS1 or LX series. Ensure thermal design accounts for QFN-56 package limitations. Check humidity sensitivity handling requirements during assembly. Validate that factory-programmed LDO voltages meet system specifications.

Power Management - Specialized Selection Notes

Choose this variant over user-programmable versions if fixed LDO outputs are sufficient. Consider the 16 MHz frequency for smaller passive components compared to lower-frequency regulators. Evaluate the 4.5 A per channel capability against peak load requirements. Compare thermal dissipation needs in the QFN-56 package against alternative packages.

Power Management - Specialized Part Context

This component belongs to the MC34VR500 series, designed specifically for complex multi-rail applications. It complements other NXP PMICs like the MC34PF4210 used with i.MX 8M processors. The series targets high-performance networking and computing systems requiring multiple synchronized power rails.

Power Management - Specialized Replacement Considerations

MC34VR500V1ESR2 offers triple user-programmable LDOs instead of factory-programmed ones. MC34VR500V3ESR2 provides similar functionality with different LDO configurations. Verify pinout and electrical parameter compatibility before substitution.
