Advance Information

Document Number: MC34VR500

Rev. 8.0, 8/2018

Multi-output DC/DC regulator for

QorIQ LS1/T1 family of

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.

Features:

• Four buck converters:

• SW1: 4.5 A

• SW2: 2.0 A

• SW3: 2.5 A

• SW4: 1.0 A, (VTT tracking regulator)

• Five general purpose linear regulators

• DDR termination reference voltage (DDR3L and DDR4)

• Programmable low-power modes

• I

C control of all the regulators

• Power Control Logic with processor interface and event detection

• Auto qualified AEC Q100 grade 2
