Description
- DC1997A-A, Demonstration Board using LTC3838EUHF-1 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. The same reference can be set from 0.8V to 1.5V with a potentiometer or the 2nd channel can regulate to a source external to the board. Both channels on the DC1997A-A version are regulated to the internal reference
