- DC1997A-B, Demonstration Board using LTC3838EUHF-2 high current, dual output synchronous buck converter. It provides two outputs of 1.5V/20A and 1.2V/20A over an input voltage range of 4.5V to 14V at a switching frequency of 300kHz. Applications requiring the output to be adjusted with an external reference can be implemented with the DC1997A-B assembly. Such applications include adaptive voltage scaling optimization (AVSO) where the processor voltage is adjusted to achieve optimal efficiency, wide output voltage applications controlled by a DAC, or margining
