MC34VR500VAES中文资料Regulator, Buck, Quad with up to 4.5A Output and Triple User-programmable LDOs, QFN 56数据手册恩XP规格书

描述 Description

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.
