Modifications
The printed-circuit board (PCB) for this EVM is designed to accommodate both the fixed and adjustable
versions of this IC. If the fixed version is installed, R1 and R3 are replaced with a 0-Ω resistor and R2 is
open. Extra positions are available for additional input and output capacitors.
1.3.1
Adjustable-Output IC U1 Operation
U1 is configured for evaluation of the adjustable-output version. This unit is set to 5 V. Resistors R1, R2
and R3 can be used to set the output voltage between 2 V and 9 V. See the data sheet for recommended
values.
1.3.2
Fixed-Output Operation
U1 can be replaced with the fixed version for evaluation. With the fixed version, R1 and R3 need to be
replaced with a 0-Ω resistor; R2 position is open.
