Analog Devices Inc. EVAL-LT3074 Evaluation Board

Analog Devices Inc. EVAL-LT3074 Evaluation Board is designed to evaluate the functionalities of the LT3074 dropout linear regulators. This evaluation board is capable of standalone operation without PMBus programming. The EVAL-LT3074 evaluation board 3A maximum output current and I2C/PMBus communication. The jumper selects bias mode of either external bias voltage or 3.3V internal logic power from the PMBus interface. This evaluation board features LED indication of POWER ON, POWER GOOD, and PMBus ALERT. A 6-pin 0.1-inch pitch connector implements Pmod Type 6 I2C. The banana jacks minimize VIN and VOUT connection voltage drops. The EVAL-LT3074 evaluation board comes in a 22-lead (3mm x 4mm) LQFN package.
