SMART VOUT LOW POWER THRESHOLD (P1) REGISTER

Table 129. Register 0xFE44—Smart VOUT Low Power Threshold (P1)

Bits

Bit Name

R/W

Description

[15:13]

RSVD

Reserved.

[12:0]

R/W

These bits set the threshold value for low power mode operation when the smart output

voltage function is enabled. When the input power is lower than this value, the output voltage

is VOL1 for low line input and VOH1 for high line input.

SMART VOUT HIGH POWER THRESHOLD (P2) REGISTER

Table 130. Register 0xFE45—Smart VOUT High Power Threshold (P2)

Bits

Bit Name

R/W

Description

[15:13]

RSVD

Reserved.

[12:0]

R/W

These bits set the threshold value for high power mode operation when the smart output

voltage function is enabled. When the input power is higher than this value, the output

voltage is VOL2 for low line input and VOH2 for high line input.
