LTM4664 Demo Board | 48VIN, Dual 25A μModule Regulator With Digital Power System Management
Analog Devices Inc.
Demonstration circuit 2672A-A is a complete non-isolated 48V input, dual-output, high efficiency, high density µModule regulator with 30V to 58V input range. Each output can supply 25A maximum load current. The demo board has a LTM4664 µModule regulator, which is a dual 25A or single 50A step-down regulator with digital power system management. Please see the LTM4664 datasheet for more detailed information.
DC2672A-A 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/DC converter. To fully explore the extensive power system management features of the part, download the GUI software LTpowerPlay™ onto your PC and use ADI’s I2C/SMBus/PMBus dongle DC1613A to connect to the board. 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.

3.3V VIN, Dual 2A, 6MHz Synchronous Step-Down Regulators at 1.8V and 2.0V Outputs, in a 0.71cm2 Solution
Analog Devices Inc.
Demonstration Circuit DC2748A features the LTC3315B dual 5V, 2A Synchronous Step-Down DC/DC regulators operating at 6MHz. One regulator provides a 1.8V output
and the other provides 2.0V, both up to a 2A load. The LTC3315B supports adjustable output voltages from 0.5V to VIN, operating frequencies from 3MHz up to 10MHz. The LTC3315B is a compact, high efficiency, and high speed synchronous monolithic step-down switching regulator. Fast minimum on-time of 25ns enables high
VIN to low VOUT conversion at high frequency.
The DC2748A operating mode may be selected as Burst Mode operation, Skip mode or Forced Continuous (FC) mode. Setting JP1 to the FC/SYNC position will allow the
LTC3315B to sync to a clock frequency from 3MHz to 10MHz. The LTC3315B operates in Forced Continuous mode when syncing to an external clock.
The LTC3315B data sheet gives a complete description of the device, operation and application information. The data sheet must be read in conjunction with the demo manual. The LTC3315B is assembled in a 2mm × 2mm LQFN package with exposed pads for low thermal resistance. The PCB Considerations section in the data sheet.
The Efficiency vs Load graph on the demo manual shows the efficiency and the power loss of the circuit with a 3.3V input in Burst Mode operation.

LTM4681 Demo Board | PolyPhase Single Output Step-Down µModule Regulator with Digital PSM: 4 × LTM4681 at 480A
Analog Devices Inc.
Demonstration circuit DC3082A-C features the LTM4681: the wide input and output voltage range, high efficiency and power density, high current PolyPhase® single output DC/DC step-down μModule® regulator with digital power system management. DC3082A-C is configured as 16-phase single output using 4× LTM4681. The factory default input voltage is 12V typical, output voltage is 1V at 480A typical or 500A peak with recommended 400LFM forced airflow. The demo board output voltages can be adjusted from 0.6V to 1V. Programming the output voltages to any value that is greater than 1V, requires derating output current based on thermal derating curves provided in the data sheet of the LTM4681. Heat sink or other appropriate electronic cooling systems can also be used in conjunction with forced airflow to further optimize the output power when the output is on and loaded with maximum output current. The factory default switching frequency is preset at 350kHz typical. DC3082A-C comes with PMBus interface and digital power system management functions. An onboard 12-pin connector is available for users to connect the dongle DC1613A to the demo board, provides an easy way to communicate and program the part using LTpowerPlay® software development tool. LTpowerPlay software and I2C/PMBus/SMBus dongle DC1613A allows users to monitor real time telemetry of input and output voltages, input and output current, switching frequency, internal IC die temperatures, power stage component temperatures and fault logs. Programmable parameters include device address, output voltages, control loop compensation, switching frequency, phase interleaving, DCM or CCM mode of operation, digital soft-start, sequencing and time based shutdown, fault responses to input and output overvoltage, output overcurrent, IC die and power component overtemperature.
The LTM4681 is available in a thermally enhanced, low profile 330-Lead (15mm × 22mm × 8.17mm) BGA package. It is recommended to read the data sheet and the demo manual of LTM4681 prior to use or making any hardware changes to DC3082A-C.
