Description

LTM4630EY-1

High Efficiency, PolyPhase 70A

Step-Down Power µModule™ Regulator

Demonstration Circuit 2164A-A 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-A can deliver nominal 70A 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-A 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-A.

Quick start proceDure

Demonstration circuit 2164A-A is easy to set up to

evaluate the performance of PloyPhase 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-A can be conﬁgured to a dual

outputs conﬁguration with VOat 52A 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).
