LTM4630EV

High Efficiency, PolyPhase

regulator. The input voltage is from 4.5V to

15V. The output voltage is jumper selectable from 0.9V

to 1.8V. The DC2007A-A can deliver a nominal 70A output

current. As explained in the data sheet, output current

derating is necessary for certain VIN, VOUT, and thermal

conditions. The LTM4630 on the DC2007A-A always

operates 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

is tightly regulated between “VO+” and “VO-” through

remote output voltage sensing which improves output

voltage regulation at heavy loads. These features and

the availability of the LTM4630EV in a compact 16mm ×

16mm × 4.41mm LGA package make it ideal for use in

many high density point-of-load regulation applications.

The LTM4630 data sheet must be read in conjunction with

this demo manual for working on or modifying the demo

circuit DC2007A-A.

Demonstration circuit DC2007A-A is easy to set up to

evaluate the performance of PolyPhase operation of the

LTM4630EV. Due to the high input/output current, the user

should select the proper input supply/load/cable which

can sustain the full load operation. It’s recommended to

pull the 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

1.0VOUT 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 the

ON position. The output voltage between “VO+” and

“VO-” should be 1.0V ±1.5% (0.985V ~ 1.015V).

4. Once the proper output voltage 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 an optional load transient test, apply an

adjustable pulse signal between “IOSTEP CLK” and the

“GND” test point. Pulse amplitude (3V ~ 3.5V) sets the

load step current amplitude. The output transient current

can be monitored at the BNC connector, J8 (5mV/A). The

pulse signal should be a very small duty cycle (<10%)

to limit the thermal stress on the transient load circuit.

6. (Optional) The LTM4630 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 can track another

supply. The output voltage tracks the voltage on TRACK

when a valid signal is applied on the test point.

8. (Optional) The DC2007A-A can be configured to a dual

output configuration with VO at 52.5A load current and

VO2 at 18A load current. Stuff a 0Ω resistor on R61

and a 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).
