14-channel power management integrated circuit (PMIC) for audio/video applications
10.4.4.3.6 SW1A/B/C specifications
Table 52.ꢀSW1A/B/C electrical characteristics
All parameters are specified at TMIN to TMAX (see Table 4), VIN = VINSW1x = 3.6 V, VSW1x = 1.2 V, ISW1x = 100 mA,
SW1x_PWRSTG[2:0] = [111], typical external component values, fSW1x = 2.0 MHz, unless otherwise noted. Typical values
are characterized at VIN = VINSW1x = 3.6 V, VSW1x = 1.2 V, ISW1x = 100 mA, SW1x_PWRSTG[2:0] = [111], and 25 °C, unless
otherwise noted.
