Current-Limit Trim
R/W
This register contains the current-sense trim level setting at which current limiting starts. Five
bits. Setting all bits to 1 results in maximum current limit (130%).

Current Share Offset
R/W
This register contains the current-share offset trim level. Writing 00h corresponds to the
minimum offset. FFh corresponds to maximum offset. See the Current Limit Error Amplifier
section in the Table 1 for more information.

Current Share Slope
R/W
This register contains current share slope trim level. Increasing this results in a steeper slope
for the current share. This register is normally written to during the user calibration. It is used
with Reg15h for trimming the current share.

Load OV Trim
R/W
Load OV Trim. This range is programmable from 105% to 120% of the nominal load voltage. 00h
corresponds to 105%. Each LSB results in an increase of 1.6 mV.

local_uvp
R/W
This register contains the local undervoltage settings. This can be programmed from 1.3 V to
2.1 V when the nominal voltage is 2 V. Each LSB increases the UV clamp setting by 3.1 mV. See
the Local Overvoltage specifications in Table 1.
