MC34VR500 | Multi-Output DC/DC Regulator

Overview

The NXP^® MC34VR500 power management solution for network processor systems is a high-efficiency, quad buck regulator with up to 4.5 A output and five user-programmable LDOs.

With four buck regulators and five LDO output channels, the MC34VR500 powers more than the network processor, significantly reducing design complexity and the overall bill of materials.
Highly integrated MC34VR500 output voltage, frequency, and turn-on sequence is user programmable using I2C.
Incorporated into multiple QorIQ^® LS1 networking communications processor reference platform, providing platform-level solutions from a single supplier to enable faster time to market and reduced engineering effort.

Features

Optimized to work with QorIQ^® LS102x communications processors (LS1020A, LS1021A, LS1022A)
V_in = 3.3 Vbus (2.8 V to 4.5 V supply)
High full load efficiency with 91% peak
High Integration
- Four independent buck converters
- Five user-programmable LDOs
