Notes

45.

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

46.

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



(VINSW3x - VSW3x) = ISW3x* (DCR of Inductor +RONSW3xP + PCB trace resistance).

Table 71. SW3A/B Electrical Characteristics (continued)

All parameters are specified at TA = -40 to 85 °C, VIN = VINSW3x = 3.6 V, VSW3x = 1.5 V, ISW3x = 100 mA,

SW3x_PWRSTG[2:0] = [111], typical external component values, fSW3x = 2.0 MHz, single phase and independent mode unless,

otherwise noted. Typical values are characterized at VIN = VINSW3x = 3.6 V, VSW3x = 1.5 V, ISW3x = 100 mA,

SW3x_PWRSTG[2:0] = [111], and 25 °C, unless otherwise noted.
