DEMO MANUAL DC2722A

DESCRIPTION

LTM4686 Ultrathin Dual 10A or Single 20A µModule Regulator

With Digital Power System Management

Demonstration circuit 2722A is a dual-output, high effi-ciency, high density, µModule regulator with 2.7V to 17V input range. Each output can supply 10A maximum load current. The demo board has a LTM4686 µModule regula-tor, which is a dual 10A or single 20A step-down regula-tor with digital power system management. Please see LTM4686 data sheet for more detailed information.

DC2722A powers up to default settings and produce 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 LTC’s I2C/SMBus/PMBus dongle DC1613A to connect to

DEMO MANUAL DC2722A

QUICK START PROCEDUREDemonstration circuit 2722A is easy to set up to evaluate the performance of the LTM4686EV. 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 (2.7V-17V*) and GND (input return).

2. Connect the 1.0V output load between VOUT0 and GND (Initial load: no load).

3. Connect the 1.8V output load between VOUT1 and GND (Initial load: no load).

4. Connect the DVMs to the input and outputs. Set default jumper position: JP1: ON; JP2: ON.

5. Turn on the input power supply and check for the proper output voltages. VOUT0 should be 1.0V ±0.5%, and VOUT1 should be 1.8V ±0.5%.

6. Once the proper output voltages are established, adjust the loads within the operating range and observe the output voltage regulation, ripple voltage and other parameters.

7. Connect the dongle and control the output voltages from the GUI. See “LTpowerPlay GUI for the LTM4686 Quick Start Guide” for details.

Note: When measuring the output or input voltage rip-ple, 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.

PERFORMANCE SUMMARY Specifications are at TA = 25°C

You can use a PC to reconfigure the power management features of the LTM4686 such as: nominal VOUT, mar-gin set points, OV/UV limits, temperature fault limits,

sequencing parameters, the fault log, fault responses, GPIOs and other functionalities. 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 system management ICs and μModules, including the LTM4675, LTM4676, LTM4677, LTM4686, LTC3880, LTC3882 and LTC3883. 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 multichip configuration file that can be saved and reloaded at a later time. LTpowerPlay provides unprecedented diagnos-tic 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 LTM4675, LTM4676, LTM4677, LTM4686, LTC3880, LTC3882, LTC3883’s demo system, or a customer board. The soft-ware 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: ltpowerplay

To access technical support documents for LTC Digital Power Products visit the LTpowerPlay Help menu. Online help also available through the LTpowerPlay.

LTPOWERPLAY QUICK START PROCEDUREThe following procedure describes how to use LTpow-erPlay to monitor and change the settings of LTM4686.

1. Download and install the LTPowerPlay GUI:

ltpowerplay

2. Launch the LTpowerPlay GUI.

a. The GUI should automatically identify the DC2722A. 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 LTM4686 is communicating:

c. In the Toolbar, click the “R” (RAM to PC) icon to read the RAM from the LTM4686. This reads the configuration from the RAM of LTM4686 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 LTM4686. 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.
