SW1A/B specifications

Table 47. SW1A/B electrical characteristics

All parameters are specified at Consumer TA = -40 to 85 °C and Extended Industrial TA = -40 to 105 °C, VIN = VINSW1x = 3.6 V, VSW1AB

= 1.2 V, ISW1AB = 100 mA, SW1AB_PWRSTG[2:0] = [111], typical external component values, fSW1AB = 2.0 MHz, unless otherwise noted.

Typical values are characterized at VIN = VINSW1x = 3.6 V, VSW1AV = 1.2 V, ISW1AB = 100 mA, SW1AB_PWRSTG[2:0] = [111], and 25 °C,

unless otherwise noted.
