Description
LTM4630EY-1
High Efficiency, PolyPhase 105A
Step-Down Power µModule™ Regulator
Demonstration Circuit 2164A-B features a PolyPhase
®
design using the LT M
®
4630EY-1 (A-grade), the high ef-
ficiency, high density, dual 18A, switch mode step-down
power module regulator. The input voltage is from 4.5V
to 15V. The output voltage is jumper selectable from 0.9V
to 1.8V. DC2164A-B can deliver nominal 105A output
current. As explained in the data sheet, output current
derating is necessary for certain VIN, VOUT, and thermal
conditions. The LTM4630-1A on DC2164A-B always
operate in continuous conduction mode. The switching
frequency can be programmed through a resistor or can
be synchronized to an external clock signal. The board
allows the user to program how its output voltage ramps
up and down through the TRACK pin. The output voltage

respective owners.
is tightly regulated between VO+and VO–through remote
output voltage sensing which improves output voltage
regulation at heavy loads. The LTM4630-1A has ±0.8%
total DC errors. These features and the availability of the
LTM4630EY-1 in a compact 16mm × 16mm × 5.01mm
BGA package make it ideal for use in many high-density
point-of-loadregulation applications. The LTM4630-1 data
sheet must be read in conjunction with this demo manual
for working on or modifying the demo circuit DC2164A-B.

Quick start proceDure
Demonstration circuit 2164A-B is easy to set up to
evaluate the performance of PolyPhase operation of the
LTM4630EY-1. Due to the high input/output current, user
should select the proper input supply/load/cable which
can sustain the full load operation. It’s recommended to
pull load current from J2 and J4. The load current pulled
from J5 and J6 shouldn’t exceed 18A. Please refer to
Figure 2 for proper measurement setup and follow the
procedure below:
1. Place jumpers in the following positions for a typical
1VOUT application:
JP1 JP2 JP4 ~ JP8
CLK RUN VOUT SELECT
INT OFF ON JP5/1.0V
2. With power off, connect the input power supply, load
and meters as shown in Figure 2. Preset the load to 0A
and VIN supply to 12V.
3. Turn on the power supply at the input. Place JP2 to
ON position. The output voltage between VO+and VO–
should be 1V ±0.8% (0.992V ~ 1.008V).
4. Oncethe proper outputvoltage is established,adjust the
load within the operating range and observe the output
voltage regulation, output voltage ripple, efficiency
and other parameters. Output voltage ripple should
be measured at J7 with BNC cables. 50Ω termination
should be set on the oscilloscope or BNC cables.
5. (Optional) For optional load transient test, apply an
adjustable pulse signal between IOSTEP CLK and GND
test point. Pulse amplitude (3V~ 3.5V) sets the load
stepcurrent amplitude. The output transient current can
be monitored at the BNC connector J8 (5mV/A). The
pulse signal should be very small duty cycle (<10%)
to limit the thermal stress on the transient load circuit.
6. (Optional) LTM4630-1 can be synchronized to an
external clock signal. Place the JP1 jumper on EXT
and apply a clock signal (0V~ 5V, square wave) on
the EXT_CLK test point.
7. (Optional) The outputs of LTM4630-1 can track another
supply. The output voltage tracks the voltage on TRACK
when a valid signal is applied on the test point.
8. (Optional) DC2164A-B can be configured to a dual
outputs configuration with VOat 87A load current and
VO2 at 18A load current. Stuff 0Ω resistor on R61 and
0.1µF on C14. Remove R22, R23, R24, R26, R27, R28,
R32, R33, R35. Output voltage VO2 is set by R37 based
on the equation VO2 = 0.6V(1 + 60.4k/R37).
