DESCRIPTION
Demonstration circuit 3164A-B features the
a quad DC/DC step-down µModule
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 volt-
ages 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 simulta-
neously 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.
