regulator, a high performance high efficiency
4 output step-down regulator. The LTM4643EV has an
operating input voltage range of 4V to 20V and is able
to provide up to 3A out output current from each of its
phases. Each output’s voltage is programmable from 0.6V
to 3.3V. The LTM4643EV is a complete DC/DC point of load
regulator in a thermally enhanced 15mm × 9mm × 1.82mm
LGA package requiring only a few input and output ca-
pacitors. Output voltage tracking is available through the

TRACK/SS pin for supply rail sequencing. External clock
synchronization is also available through the CLKIN pin.
The CLKOUT pin provides for synchronization of additional
modules’ phases. The LTM4643 data sheet must be read
in conjunction with this demo manual for working on or
modifying demo circuit 2453A.
