Electrical Characteristics—Top-Level (continued)

(VSYS = VINx = 12V, VOUT1 = 0.8V (M1_RNG = 0x0), VOUT2 = 1.1V (M2_RNG = 0x1), VOUT3 = 1.8V (M3_RNG = 0x1), VOUT4 = 3.3V

(M4_RNG = 0x2), single-phase configuration, VCE = 1.8V, VIO = 1.8V, TA = TJ = -40°C to +125°C, typical values are at TA = TJ =

+25°C, unless otherwise noted. Note 2. )
