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.

LTC3803ES6 Isolated Demo Board | Flyback Controller, 36V ≤ VIN ≤ 72V, VOUT = 5V@2A
Analog Devices Inc.
Demonstration circuit 649 is a Telecom isolated DC/DC converter featuring the LTC3803 constant frequency current mode flyback controller. The DC649 converts an isolated 36V to 72V input and provides 2A of output current at 5V. The 200kHz constant frequency operation is maintained down to very light load to reduce low frequency noise generated over a wide range of load current. The converter provides high output voltage accuracy (typically ±2%) over wide load range with no minimum load requirement.

Analog Devices Inc.
The LTC3553 is a micropower, highly integrated power management and battery charger IC for single-cell Li-Ion/Polymer battery applications. It includes a PowerPath manager with automatic load prioritization, a battery charger, an ideal diode and numerous internal protection features. Designed specifically for USB applications, the LTC3553 power manager automatically limits input current to a maximum of either 100mA or 500mA. Battery charge current is automatically reduced such that the sum of the load current and the charge current does not exceed the selected input current limit. The LTC3553 also includes a synchronous buck regulator, a low dropout linear regulator (LDO), and a pushbutton controller. With all supplies enabled in standby mode, the quiescent current drawn from the battery is only 12?A. The LTC3553 is available in a 3mm ? 3mm ? 0.75mm 20-pin QFN package.
