Multi-output DC/DC regulator for
QorIQ LS1/T1 family of
34VR500
communications processors
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.
