Table 71. SW3A/B electrical characteristics

All parameters are specified at Consumer TA = -40 to 85 °C and Extended Industrial TA = -40 to 105 °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.
