LTM4681 | PolyPhase Single Output Step-Down μModule Regulator with Digital PSM: 2 × LTM4681 at 240A
Analog Devices Inc.
Demonstration circuit 3082A-A 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-A is configured as 8-phase single output using 2 × LTM4681. The factory default input voltage is 12V typical, output voltage is 1V at 240A typical or 250A 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-A 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 overtemperatures.
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 demo manual of LTM4681 prior to using or making any hardware changes to DC3082A-A.

Evaluating the ADP8861 Charge Pump, 7-Channel Smart LED Driver with I2C Interface
Analog Devices Inc.
The ADP8860SHIELD-EVALZ and the ADP8861SHIELD-EVALZ incorporate light emitting diodes (LEDs) for quick and easy evaluation of the ADP8860 and the ADP8861. Note that only the ADP8860SHIELD-EVALZ has dual light intensity sensors. The ADP8860SHIELD-EVALZ and the ADP8861SHIELD-EVALZ follow the form factor of a regular Arduino® shield to allow compatibility with microcontroller boards that use the same interface. These evaluation boards also incorporate a separate header dedicated to I2C communications.
The ADP8860 and the ADP8861 are 7-channel LED drivers that utilizes a charge pump with selective gain for maximum efficiency. The LEDs driven by either device are programmable for maximum current and fade in and out times via the I2C interface. Only the ADP8860 has a programable light intensity threshold that can be set via the I2C interface of the device. Each channel can handle up to 30 mA (typical), except for the seventh channel, which can handle 60 mA (typical). Each channel can be unified to have the same fade in time and fade out time, or each channel can have an individual fade in time and fade out time for greater flexibility.
For full details on the ADP8860 and the ADP8861, see the ADP8860 and the ADP8861 data sheets, which should be consulted in conjunction with the user guide when using these evaluation boards.

LT3991EMSE Demo Board | 55V, 1.2A, Step-Down Regulator with 2.8µA Quiescent Current
Analog Devices Inc.
Demonstration circuit 1526 is a monolithic step-down DC/DC switching regulator featuring the LT3991. The switching frequency is adjustable up to 2MHz. The demo circuit is designed for 3.3V, 1.2A output from a 4.5V to 55V input. The wide input range of the LT3991 allows a variety of input sources including automotive batteries and 24V industrial supplies. Low ripple Burst Mode increases the efficiency at the light load while keeping the output ripple below 15mV. The part is in shutdown when the EN pin is low and active when the pin is high. The threshold of the EN pin is accurate at 1.01V with 30mV of hysteresis. When VIN is above 6V, adding a resistor divider from VIN to EN can program the LT3991 to regulate the output only when VIN is above a desired voltage. The circuit consumes only 2.8μA of quiescent current. The boost diode, control and logic circuit are integrated to reduce the components count and solution size. The current mode control scheme creates fast transient response and good loop stability.
