FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS

6.4.4.4.7

SW3A - SW3B independent outputs

SW3A and SW3B can be configured as independent outputs as shown in Figure 23, providing flexibility for applications requiring more

voltage rails with less current capability. Each output is configured and controlled independently by its respective I2C registers as shown

in Table 66.

SW3A/B Setup and Control Registers

SW3A/B output voltage is programmable from 0.400 V to 3.300 V; however, bit SW3x[6] in register SW3xVOLT is read-only during normal

operation. Its value is determined by the default configuration, or may be changed by using the OTP registers. Therefore, once SW3x[6]

is set to “0”, the output is limited to the lower output voltages from 0.40 V to 1.975 V with 25 mV increments, as determined by bits

SW3x[5:0]. Likewise, once bit SW3x[6] is set to "1", the output voltage is limited to the higher output voltage range from 0.800 V to 3.300 V

with 50 mV increments, as determined by bits SW3x[5:0].

In order to optimize the performance of the regulator, it is recommended only voltages from 2.00 V to 3.300 V be used in the high range

and the lower range be used for voltages from 0.400 V to 1.975 V.

The output voltage set point is independently programmed for normal, standby, and sleep mode by setting the SW3x[5:0],

SW3xSTBY[5:0], and SW3xOFF[5:0] bits respectively; however, the initial state of the SW3x[6] bit is copied into the SW3xSTBY[6] and

SW3xOFF[6] bits. Therefore, the output voltage range remains the same on all three operating modes. Table 65 shows the output voltage

coding valid for SW3x.

Note: Voltage set points of 0.6 V and below are not supported.
