APPLICATIONS INFORMATION
Current Sense Resistor
The traces leading to and from the sense resistor
can be significant error sources. With small value
sense resistors, trace resistance shared with the
load can cause significant errors. It is recom-
mended to connect the sense resistor pads di-
rectly to the CSP and CSN pins using

Current Limit Setting
If output current hits current limit, output voltage
drops to keep the current to a constant value.
The following equation calculates the constant
current limit.
