Description
[2:0]
Load line setting
R/W
These bits specify how much the output voltage decreases from nominal at full load. The amount
of output resistance introduced can be calculated as follows (these bits specify the value of N):
ROUT
= 0.1 × VOUT_NOM × CS2 RSENSE/(CS2 Range × 2N)
For more information, see the Digital Load Line and Slew Rate section.

[5:0]
Fast OVP threshold
R/W
These bits set the threshold for the fast OVP analog comparator. This threshold is programmable
from 0.8 V to 1.6 V. Setting this value to 0x00 corresponds to a 0.8 V threshold. Setting this value to
0x3F corresponds to a 1.6 V threshold. Each LSB increments the threshold by 12.5 mV. The fast OVP
threshold can be set using the following formula:
Fast_OVP_Threshold = (Bits[5:0] × 0.8 V/63) + 0.8 V
Table 56. Register 0x38—VS1 Trim
Bits
Bit Name
R/W
Description
7
Trim polarity
R/W
1 = negative gain is introduced.
0 = positive gain is introduced.
[6:0]
VS1 trim
R/W
These bits set the amount of gain trim that is applied to the VS1 ADC reading. This register trims
the voltage at the VS1 pin for external resistor tolerances. When there is 1 V on the VS1 pin, this
register is trimmed until the VS1 voltage value (Register 0x15[15:4]) reads 2560 (0xA00).

1 = negative gain is introduced.

VS2 trim
R/W
These bits set the amount of gain trim that is applied to the VS2 ADC reading. This register trims
the voltage at the VS2 pin for external resistor tolerances. When there is 1 V on the VS2 pin, this
register is trimmed until the VS2 voltage value (Register 0x16[15:4]) reads 2560 (0xA00).
Table 58. Register 0x3A—VS3 Trim
Bits
Bit Name
R/W
Description

Trim polarity
R/W
1 = negative gain is introduced.
0 = positive gain is introduced.
[6:0]
VS3 trim
R/W
These bits set the amount of gain trim that is applied to the VS3 ADC reading. This register trims
the voltage at the VS3 pins for external resistor tolerances. When there is 1 V on each VS3 pin, this
register is trimmed until the VS3 voltage value (Register 0x17[15:4]) reads 2560 (0xA00). The VS3
trim must be performed before the load OVP and load UVP trims are performed.
