The NXP® MC34VR500V1ES 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 MC34VR500V1ES powers more than the network processor, significantly reducing design complexity and the overall bill of materials.
- Highly integrated MC34VR500V1ES 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.
