DC1540B
Analog Devices Inc.
The LTC2977 is an 8-channel Power System Manager used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry and create fault logs. PMBus commands support power supply sequencing, precision point-of-load voltage adjustment and margining. DACs use a proprietary soft-connect algorithm to minimize supply disturbances. Supervisory functions include overvoltage and undervoltage threshold limits for eight power supply output channels and one power supply input channel, as well as over and under temperature limits. Programmable fault responses can disable the power supplies with optional retry after a fault is detected. Faults that disable a power supply can automatically trigger black box EEPROM storage of fault status and associated telemetry. An internal 16-bit ADC monitors eight output voltages, one input voltage, and die temperature. In addition, odd numbered channels can be configured to measure the voltage across a current sense resistor. A programmable watchdog timer monitors microprocessor activity for a stalled condition and resets the microprocessor if necessary. A single wire bus synchronizes power supplies across multiple LTC Power System Management (PSM) devices. Configuration EEPROM with ECC supports autonomous operation without additional software.APPLICATIONS Computers and Network Servers Industrial Test and Measurement High Reliability Systems Medical Imaging Video

LTC3424EMS Demo Board | 1V ≤ VIN ≤ 1.6V, VOUT = 1.8V @ 600mA
Analog Devices Inc.
Demonstration circuit 516A-B is a low output voltage, synchronous boost converter featuring the LTC3424. The LTC3424 is ideal for applications that require an output voltage between 1.5V to 2.6V from a single alkaline or NiCd/NiMH cell. A bias voltage (VDD) of 2.7V to 5.5V is required to power the internal circuitry. The input voltage (VIN) range is 1V to 1.6V, but once up and running, the device can operate with an input voltage as low as 0.5V. The output voltage is set at 1.8V. For a 1V minimum battery voltage, the LTC3424 can provide 600mA.
