Product Details

Demonstration circuit DC1617A is a dual output synchronous buck converter featuring the LTC3855EFE in a high density, two sided drop-in layout with power components on the top and the control circuit on the bottom. The package style for the LTC3855EFE is a 38-lead TSSOP. The board comes in two assembly types. The –A assembly provides 2.5V/15A and 1.8V/15A from a 4.5V to 26V input. DCR inductor sensing is used to provide the highest efficiency. The current limit is NTC compensated to provide the minimal amount of variation over temperature. The -A also features remote sensing for V_OUT2.
