NXP Semiconductors MC34VR500 Multi-Output DC/DC Regulators
NXP's MC34VR500 Multi-Output DC/DC Regulators are a high-efficiency, quad buck regulator with up to 4.5A output and five user-programmable LDOs. With quad 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 (BOM). The highly integrated MC34VR500 output voltage, frequency and turn-on sequence is user programmable using I2C. The MC34VR500 is ideally suited to power system solutions based on QorIQ LS1 networking communications processors with unique programmable multiple DC/DC and LDO outputs. The MC34VR500 has been incorporated into multiple QorIQ LS1 networking communications processor reference platforms. This collaboration provides platform-level solutions from a single supplier to enable faster time to market and reduced engineering effort.Features
