FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS
6.4.4.3
SW1A/B
SW1A/B is a 2.5 A single phase regulator. The SW1ALX and SW1BLX pins should be connected together on the board.
SW1_CONFIG[1:0] = 01 is the only configuration supported.
The single phase configuration is programmed by OTP by using SW1_CONFIG[1:0] bits in the register map Extended page 1, as shown
in Table 38.
.
SW1A/B single phase
In this configuration, SW1A/B is connected as a single phase with a single inductor. This configuration allows reduced component count
by using only one inductor for SW1A/B. Figure 11 shows the physical connection for SW1A/B in single phase.
Figure 11. SW1A/B single phase block diagram
Both SW1ALX and SW1BLX nodes operate at the same DVS, frequency, and phase configured by the SW1ABCONF register.
