SW3A/B

SW3A/B are 1.25 to 2.5 A rated buck regulators, depending on the configuration. Table 29 describes the available switching

modes and Table 30 show the actual configuration options for the SW3xMODE[3:0] bits.

SW3A/B can be configured in various phasing schemes, depending on the desired cost/performance trade-offs. The following

configurations are available:

• A single phase

• A dual phase

• Independent regulators

The desired configuration is programmed in OTP by using the SW3_CONFIG[1:0] bits.Table 63 shows the options for the

SW3CFG[1:0] bits.
