Configuring with LTpowerPlay
To reconfigure the PSM features of the LTP8800-2, use a PC with the
LTpowerPlay software and the DC1613A USB-to-SMBus controller. Follow the
software instructions for configuring nominal VOUT, margin set points, limits,
fault responses, and other functionalities.

General Description
The DC3190B-E is a high current, high density, high efficiency open-frame μModule® regulator with 45V to 65V input range. The DC3190B-E evaluation board has an LTP®8800-2 μModule (micromodule) regulator which provides microprocessor 0.75V voltage from 54V power distribution architecture with digital power system management (PSM). The maximum output current for the evaluation board is 135A. See LTP8800-2 data sheet for more detailed information.
The DC3190B-E powers up to default settings and produces power based on configuration resistors without the need for any serial bus communication. This allows easy evaluation of the dc-to-dc converter. To fully explore the extensive PSM features of the DC3190B-E, download LTpowerPlay® graphical user interface (GUI) software to your PC and use Analog Devices I2C/SMBus/PMBus dongle DC1613A to connect to the evaluation board. The LTpowerPlay allows the user to reconfigure the part on-the-fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature, and fault status.

Quick Start
Required Equipment
- Power supply #1: capable of sourcing 65V and 10A
- Power supply #2: capable of sourcing 7V and 1A
- Power supply #3: capable of sourcing 3.3V and 1A
- Electronic load: capable of sinking 0.75V and 135A
- Two digital multimeters (DMMs)
Procedure
The DC3190B-E is easy to set up to evaluate the performance of the LTP8800-2.
See Figure 2 for the proper measurement equipment setup and follow the
procedure below.
- With power off, connect the input power supply to VIN (45V to 65V) and GND.
- With power off, connect the auxiliary power supply to 7V0 (7V) and GND.
- With power off, connect the auxiliary power supply to 3V3 (3.3V) and GND.
- With power off, connect the load from VOUT to GND.
- Connect the DMMs to the input and output.
- Turn on the 3.3V and 7V auxiliary power supply before turning on the input power supply.
- Turn on the input power supply and check for the proper output voltage. The VOUT should be 0.75V ±0.5%.
- Once the input and output voltages are properly established, adjust the load current within the operating range of 0A to 135A max. Observe the output voltage regulation, output voltage ripples, load transient response, and other parameters.
- Connect the dongle and control the output voltages from the GUI (optional).
- Turn off the input power supply before turning off the auxiliary power supply.
- Turn off the 3.3V and 7V auxiliary power supply.
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.
