Notes

55.

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

56.

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 78. SW3A/B electrical characteristics (continued)

All parameters are specified at TMIN to TMAX (See Table 3), 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/dual 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.
