Notes

47.

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

48.

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 62. SW2 electrical characteristics (continued)

All parameters are specified at PF0100Z TA = -40 °C to 85 °C, PF0100AZ TA = -40 °C 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.
