Evaluation Board Schematic
Components
I.C.
CAPACITORS
* In order to meet LM2750 minimum capacitance requirements, 10V is the minimum recommended voltage rating for all
capacitors. This elevated rating recommendation accounts for capacitace degradation due to DC bias, a common property of
ceramic capacitors. For more information on capacitors, refer to the LM2750 datasheet.
