Modifications
The printed-circuit board (PCB) for this EVM is designed to accommodate both the fixed and adjustable
voltage versions of this integrated circuit (IC). Additional input and output capacitors can also be added,
and the soft-start time can be changed. Finally, the loop response of the IC can be measured.

Fixed Output Operation
U1 can be replaced with the fixed-voltage version of the IC for evaluation. For fixed-voltage version
operation, replace R2 with a 0-
operation, replace R2 with a 0-
Ω resistor and remove R1.
