SWBST specifications

Table 90. SWBST Electrical Specifications

All parameters are specified at TMIN to TMAX (See Table 3), VIN = VINSWBST = 3.6 V, VSWBST = 5.0 V, ISWBST = 100 mA, typical external

component values, fSWBST = 2.0 MHz, otherwise noted. Typical values are characterized at VIN = VINSWBST = 3.6 V, VSWBST = 5.0 V,

ISWBST = 100 mA, and 25 °C, unless otherwise noted.
