EVAL-ADM1294EBZ

Analog Devices Inc.
The ADM1293 and ADM1294 are high accuracy integrated digital power monitors that offer digital current, voltage, and power monitoring using an on-chip, 12-bit analog-to-digital converter (ADC), communicated through a PMBus? compliant I2C interface.These devices acquire the current by measuring the voltage difference across the external sense resistor. This voltage is amplified and digitized by an internal 12-bit ADC. The same ADC can also sample the primary input voltage and an auxiliary input voltage. The internal digital block can perform multiplication of the current and primary input voltage for power calculation. The ADM1293/ADM1294 also feature a power accumulator for energy metering. An industry-standard PMBus interface allows a master controller to read back these data from the device. The master controller can then combine this information with a known sense resistor value to calculate the current, voltage, power, and energy consumption over time on the monitored rail.In conditions such as overcurrent, overvoltage, undervoltage, and overpower, the ADM1293/ADM1294 devices can generate an interrupt signal to the microprocessor through the GPOx/ALERTx outputs. The threshold for these conditions is digitally programmed via PMBus.The ADM1293 is designed for high-side supply monitoring with a voltage monitoring range from 0 V to 20 V. The ADM1294 is designed for low-side supply monitoring. Its integrated shunt regulator allows it to be powered and to monitor supply in wide voltage ranges.The ADM1293/ADM1294 are available in 4 mm ? 4 mm 16-lead LFCSP and 14-lead TSSOP packages with a specified operating ambient temperature range from ?40?C to +105?C for the ADM1293 and an operating junction temperature range from ?40?C to +105?C for the ADM1294.Applications Power monitoring/power budgeting Central office equipment Telecommunications and data communications equipment PCs/servers

LTM4630A Demo Board | Dual 18A or Single 36A μModule Regulator

Analog Devices Inc.
Demonstration circuit 2268A-F is a high efficiency, high density, dual 8A, switch mode step-down power supply on a compact 1.5' × 1.2' PCB. It features the LTM4630A μModule® regulator. The input voltage is from 4.5V to 15V. The output voltage is programmable from 0.6V to 5.3V. DC2268A-F can deliver up to 18A maximum in each channel. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT, and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the resistor jumper (R1/R2) selects pulse-skipping mode for noise sensitive applications or Burst-Mode® in less noise sensitive applications. Two outputs can be connected in parallel for a single 36A output solution with optional jumper resistors. The board allows the user to program how its output ramps up and down through the TRACK/SS pin. Remote output voltage sensing is available for improved output voltage regulation at the load point. An optional input inductor L1 reduces the EMI noise for noise sensitive applications. DC2268A can be easily inserted to an edge connector for testing and debugging. These features and the availability of the LTM4630A in a compact 16mm × 16mm × 4.41mm LGA package make it ideal for use in many high-density point-of-load regulation applications. The LTM4630A data sheet must be read in conjunction with this demo manual for working on or modifying the DC2268A-F.
