Notes

43.

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

44.

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 61. SW2 Electrical Characteristics

All parameters are specified at TA = -40 to 85 °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.
