Default

Description

SW3A

5:0

R/W

0x00

Sets the SW3A output voltage (Independent) or

SW3A/B output voltage (Single/Dual phase),

during normal operation mode. See Table 63 for

all possible configurations.

SW3A

0x00

Sets the operating output voltage range for SW3A

(Independent) or SW3A/B (Single/Dual phase).

Set during OTP or TBB configuration only. See

Table 63 for all possible configurations.

Name

Bit #

R/W

Default

Description

SW3ASTBY

5:0

R/W

0x00

Sets the SW3A output voltage (Independent) or

SW3A/B output voltage (Single/Dual phase),

during Standby mode. See Table 63 for all

possible configurations.

SW3ASTBY

0x00

Sets the operating output voltage range for SW3A

(Independent) or SW3A/B (Single/Dual phase) on

Standby mode. This bit inherits the value

configured on bit SW3A[6] during OTP or TBB

configuration. See Table 63 for all possible

configurations.
