Description

Demonstration circuit 3164A-B features the LTM4710‑1, 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.
