DESCRIPTION

54V Input, High Current DC/DC Power μModule with PMBus Interface Demonstration circuit 3190B-F is a high current, high density, high efficiency open-frame μModule ® regula - tor with 45V to 65V input range. The DC3190B-F demo board has a LTP8802A-1B module regulator that provides the microprocessor a 3.3V voltage from 54V power dis- tribution architecture with digital power system man - agement (PSM). The maximum output current for the DC3190B-F demo board is 140A. See the LTP8802A-1B data sheet for more detailed information. The DC3190B-F powers up to default settings and pro - duces power based on configuration resistors without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter .

BOARD PHOTO DC3190B-F , download the graphical user interface (GUI) software L TpowerPlay® onto your PC and use Analog Devices I2C/SMBus/PMBus dongle DC1613A to connect to the board. L TpowerPlay allows the user to reconfig - ure the part on-the-fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status. L TpowerPlay GUI Download The software can be downloaded at LTpowerPlay. For more details and instructions of the L TpowerPlay, see the L TpowerPlay GUI for LTP8802A-1B Quick Start Guide. Design files for this circuit board are available. Figure 1. DC3190B-F Demo Board

Rev. A PERFORMANCE SUMMARY Specifications are at TA = 25°C, Air Cooling 900LFM PARAMETER CONDITIONS MIN TYP MAX UNITS Input Voltage Range, VIN 45 65 V Output Voltage 3.29 3.30 3.31 V Default Switching Frequency 776 800 824 kHz Maximum Output Current Derating is Necessary for Certain VIN and Thermal Conditions 140 A Converter Efficiency VIN = 54V, fSW = 800kHz, VOUT = 3.30V, IOUT = 140A 93.0 % QUICK START PROCEDURE Demonstration circuit DC3190B-F is easy to set up to eval- uate the performance of the LTP8802A-1B. See Figure 2 for the proper measurement equipment setup and use the following the procedure: 1. With the power off, connect the input power supply to VIN (45V to 65V) and GND. 2. With the power off, connect the auxiliary power sup- ply to 7V0 (7V) and GND. 3. With the power off, connect the auxiliary power sup- ply to 3V3 (3.3V) and GND. 4. With the power off, connect the load from VOUT to GND. 5. Connect the digital multi meters (DMMs) to the input and output. 6. Turn on the 3.3V and 7V auxiliary power supply before turning on the input power supply. 7. Turn on the input power supply and check for the proper output voltage. VOUT should be 3.30V ±0.5%. 8. Once the input and output voltages are properly established, adjust the load current within the oper - ating range of 0A to 140A max. Observe the output voltage regulation, output voltage ripples, load tran - sient response and other parameters. 9. Connect the dongle and control the output voltages from the GUI (optional). 10. Turn off the input power supply before turning off the auxiliary power supply. 11. Turn off the 3.3V and 7V auxiliary power supply. 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.
