MC34VR500V8ESR2

Power Management - Specialized Overview

The MC34VR500V8ESR2 is a multi-output DC/DC regulator from the NXP MC34VR500 series, designed for high-performance network processor systems. It features a quad buck topology with up to 4.5A output capability and triple user-programmable LDOs. The device operates within an input voltage range of 2.8 V to 4.5 V and supports a switching frequency of 16 MHz. It is housed in a QFN-56 package and functions reliably across a temperature range of -40°C to +105°C.

Power Management - Specialized Feature Summary

• Integrates four independent buck converters capable of delivering up to 4.5A per channel.
• Includes three low-dropout regulators (LDOs) with user-configurable output voltages.
• Supports high-frequency operation at 16 MHz for compact external component sizing.

Power Management - Specialized Applications

• Powering LS1023A, LS1043, T1012, and T1023 network processors
• Supplying power for LS1024A, LX2160, and LS1046A processors
• Providing regulated rails for LS1028, LS1020A, and LS1021A systems

Power Management - Specialized Procurement Notes

Verify the specific suffix 'ESR2' against official documentation to confirm reel packaging and tape specifications. Ensure compatibility with target network processor power sequencing requirements. Cross-reference the exact part number with NXP datasheets to validate pinout and thermal characteristics before integration into final designs.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring multiple synchronized buck outputs and programmable LDOs for complex SoC architectures. It is suitable for applications needing high current density and flexible voltage regulation within a small footprint. Consider thermal management solutions given the QFN-56 package constraints under full load conditions.

Power Management - Specialized Part Context

This part belongs to the MC34VR500 series, a family of power management ICs specifically engineered for NXP's LS1 and PowerQUICC processor lines. These regulators provide integrated power solutions that reduce bill-of-materials complexity by combining multiple conversion stages into a single chip optimized for networking infrastructure.
