IMVP-6.5 VID Controllers
ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Figure 1, VIN = 10V, VCC = VDD = V SHDN = VPGD_IN = V PSI = VILIM = 5V, VDPRSLPVR = VGNDS = 0, VCSP_ = VCSN_ =
1.0000V, FB = FBAC, RFBAC = 3.57kΩ from FBAC to CSN_, [D6–D0] = [0101000]; TA = 0°C to +85°C, unless otherwise noted.
Typical values are at TA = +25°C.)
