Notes

44.

When output is set to > 2.6 V the output will follow the input down when VIN gets near 2.8 V.

45.

Accuracy specification is inclusive of load and line regulation.

46.

The higher output voltages available depend on the voltage drop in the conduction path as given by the following equation:

(VINSW2 - VSW2) = ISW2* (DCR of Inductor +RONSW2P + PCB trace resistance).

Table 56. SW2 electrical characteristics (continued)

All parameters are specified at Consumer TA = -40 to 85 °C and Extended Industrial TA = -40 to 105 °C, VIN = VINSW2 = 3.6 V, VSW2 =

3.15 V, ISW2 = 100 mA, SW2_PWRSTG[2:0] = [111], typical external component values, fSW2 = 2.0 MHz, unless otherwise noted. Typical

values are characterized at VIN = VINSW2 = 3.6 V, VSW2 = 3.15 V, ISW2 = 100 mA, SW2_PWRSTG[2:0] = [111], and 25 °C, unless

otherwise noted.
