Demonstration circuit 1126 is a high density dual output (3.3V/5A and 2.5V/5A) step down converter featuring the LTC3850EUF. The input voltage range is 6.5V to 14V. For applications that have a 5V +/- 0.5V input, the board has an optional resistor to tie the INTVCC pin to the VIN pin.
An optional DCR sense circuit allows the converter to use the inductors DCR as the sense element instead of the on-board sense resistors to save cost and board space and to improve efficiency.
