MC34VR500VCESR2

Power Management - Specialized Overview

The MC34VR500VCESR2 is a multi-output DC/DC regulator from the NXP MC34VR500 series, housed in a QFN-56 package. It features a buck topology with an input voltage range of 2.8 V to 4.5 V. The device provides four adjustable output channels capable of up to 4.5 A output current and includes three user-programmable LDOs. Operating at a switching frequency of 16 MHz, it supports a shutdown function and functions within a temperature range of -40 °C to +105 °C.

Power Management - Specialized Feature Summary

• Integrates four high-current buck regulators with triple user-programmable LDOs for flexible power distribution
• Supports wide input voltage range suitable for single-cell lithium-ion battery applications
• Enables precise load regulation through advanced control architecture

Power Management - Specialized Applications

• Portable consumer electronics requiring compact power management
• Industrial equipment needing multi-rail power sequencing
• Automotive infotainment systems

Power Management - Specialized Procurement Notes

Verify the specific suffix 'VCE' against official NXP documentation to confirm factory-programmed versus user-programmable LDO configurations. Ensure compatibility with the KITVR500EVM development kit if evaluation is required. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly planning.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring multiple independent voltage rails from a single input source. The integrated LDOs provide clean power for sensitive analog sections, while the buck converters handle high-current digital loads. Consider thermal performance and PCB layout requirements associated with the QFN-56 package.
