dc1997a-a DC1997A-A LTC3838EUHF-1 Demo Board | 4.5V ≤ VIN ≤ 14V; VOUT1 = 1.5V @ 20A, VOUT2 = 1.2V @ 20A Demonstration circuit DC1997A is a dual output synchronous buck converters featuring the LTC3838EUHF-1 (DC1997A-A) or the  LTC3838EUHF-2 (DC1997A-B). Both assemblies provide 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 LTC3838-1 and LTC3838-2 provide dual differential VOUT sensing while the dual LTC3838 (plain) has differential VOUT sensing on one channel. The "-2" version has an external reference input for channel 2. DC1997A-A
