Description

LTM4676AEY130A Step-Down μModule

Regulator with PMBus Power System Management

Demonstration circuit 2106B-B is a high efficiency, high density, µModule regulator with 4.5V to 16V input range. The output voltage is adjustable from 0.5V to 1.8V, and it can supply 130A maximum load current. The demo board has 1× LTM®4676A and 3× LTM4630 µModule regulators. The LTM4676A is a dual 13A or single 26A step-down regulator with PMBus power system management, and the LTM4630 is a dual 18A or single 36A step-down regulator. Please see LTM4676A and LTM4630 data sheets for more detailed information.

DC2106B-B powers up to default settings and produces power based on configuration resistors without the need for any serial bus communication. This allows easy evalu-ation of the DC/DC converter. To fully explore the extensive power system management features of the part, download the GUI software LTpowerPlay™ onto your PC and use

Quick start proceDureDemonstration circuit 2106B-B is easy to set up to evaluate the performance of the LTM4676AEY. Refer to Figure 2 for the proper measurement equipment setup and follow the procedure below.

1. With power off, connect the input power supply to VIN (4.5V to 16V) and GND (input return).

2. Connect the output load between VOUT0 and GND (Initial load: no load).

3. Connect the DVMs to the input and outputs. Set default switch position: SW1: ON; SW2: ON.

4. Turn on the input power supply and check for the proper output voltages. VOUT0 should be 1V ±1%.

5. Once the proper output voltages are established, ad-just the loads within the operating range and observe the output voltage regulation, ripple voltage and other parameters.

6. Connect the dongle and control the output voltages from the GUI. See “LTpowerPlay GUI for the LTM4676A Quick Start Guide” for details.

Note: When measuring the output or input voltage ripple, do not use the long ground lead on the oscilloscope probe. See Figure 3 for the proper scope probe technique. Short, stiff leads need to be soldered to the (+) and (–) terminals of an output capacitor. The probe’s ground ring needs to touch the (–) lead and the probe tip needs to touch the (+) lead.

Connecting a PC to DC2106B-B

You can use a PC to reconfigure the power management features of the LTM4676A such as: nominal VOUT, margin set points, OV/UV limits, temperature fault limits, sequenc-ing parameters, the fault log, fault responses, GPIOs and other functionality. The DC1613A dongle may be plugged when VIN is present.

LTpowerPlay Software GUI

LTpowerPlay is a powerful Windows based development environment that supports Linear Technology power sys-tem management ICs, including the LTM4676A, LTC3880, LTC3883, LTC2974 and LTC2978. The software supports a variety of different tasks. You can use LTpowerPlay to evaluate Linear Technology ICs by connecting to a demo board system. LTpowerPlay can also be used in an offline mode (with no hardware present) in order to build a mul-tichip configuration file that can be saved and reloaded at a later time. LTpowerPlay provides unprecedented diagnostic and debug features. It becomes a valuable diagnostic tool during board bring-up to program or tweak the power management scheme in a system, or to diagnose power issues when bringing up rails. LTpowerPlay utilizes the DC1613A USB-to-SMBus controller to communicate with one of many potential targets, including the LTM4676, the

LTC3880 and the LTC3883’s demo system, or a customer board. The software also provides an automatic update feature to keep the software current with the latest set of device drivers and documentation. The LTpowerPlay software can be downloaded from:

http://linear.com/ltpowerplay

LTpowerPlay QUICK START PROCEDURE

The following procedure describes how to use LTpowerPlay to monitor and change the settings of LTM4676A.

1. Download and install the LTPowerPlay GUI:

http://linear.com/ltpowerplay

Figure 10. LTpowerPlay Main Interface

7dc2106bbf


Quick start proceDure2. Launch the LTpowerPlay GUI.

a. The GUI should automatically identify the DC2106B-B. The system tree on the left hand side should look like this:

b. A green message box shows for a few seconds in the lower left hand corner, confirming that LTM4676A is communicating:

c. In the Toolbar, click the “R” (RAM to PC) icon to read the RAM from the LTM4676A. This reads the configuration from the RAM of LTM4676A and loads it into the GUI.

d. If you want to change the output voltage to a different value, like 1.5V. In the Config tab, type in 1.5 in the VOUT_COMMAND box, like this:

Then, click the “W” (PC to RAM) icon to write these register values to the LTM4676A. After finishing this step, you will see the output voltage will change to 1.5V.

If the write is successful, you will see the following message:

e. You can save the changes into the NVM. In the tool bar, click “RAM to NVM” button, as following

f. Save the demo board configuration to a (*.proj) file. Click the Save icon and save the file. Name it whatever you want.
