Multi-output DC/DC
regulator for QorIQ LS1/T1 family of communications processors
Document Number: MC34VR500 Rev. 12, 3/2021
34VR500
The 34VR500 is a high performance, highly integrated, multi-output, SMARTMOS, DC/DC
regulator solution, with integrated power MOSFETs ideally suited for the LS1/T1 family of communication processors. Integrating four switching and five linear
regulators, the 34VR500 provides power to the complete system, including the processor, DDR memory, and system peripherals.
