DESCRIPTION

Demonstration circuit 3164A-B features the LTM®4710‑1,

a quad DC/DC step-down µModule® regulator with 8A per

output, packaged in a compact (6mm × 12mm × 3.54mm)

land grid array (LGA) with pre-made solder balls.

DC3164A-B has an operating input range of 2.5V to 5.5V.

The outputs of the four channels are 0.8V, 1.0V, 1.2V, and

1.5V with 8A per output, respectively. All outputs voltages are programmable from 0.5V up to 3.6V (step-down

only). DC3164A-B operates by default at 1.5MHz and can

be adjusted by an external resistor from 1MHz to 5MHz or

by being synchronized to an external clock from 1.2MHz

to 2.6MHz. DC3164A-B also allows for the channels to be

paralleled up to 32A load current.

LTM4710-1 integrates four separate constant-frequency

peak current mode control regulators, power MOSFETs,

inductors, and other supporting discrete components.

It employs the second-generation Silent Switcher®

technologyin which it allows fast switching edges for high

efficiency at high switching frequencies, while simultaneously achieving good EMI performance. Refer to the

LTM4710-1 data sheet for more detailed information.

It is recommended to read the data sheet of the LTM4710-1

prior to making any changes to the DC3164A-B board
