Notes

42.

Supports the Coremark and 3D MM benchmark maximum current value of 2500 mA of the VDD_SOC_IN domain in the i.MX 6Dual/Quad

processors.

43.

Current rating of SW1AB supports the power virus mode of operation of the i.MX 6X processor.

Table 53. SW1A/B/C electrical characteristics (continued)

All parameters are specified at PF0100Z TA = -40 °C to 85 °C, PF0100AZ TA = -40 °C to 105 °C, 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.
