1-Phase Quick-PWM
Intel IMVP-6.5/GMCH Controllers
ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Figure 1, VIN = 12V, VDD = VCC = 5V, CLKEN pullup to 3.3V with 1.9kΩ, SHDN = SLOW = ILIM = PGDIN = VCC, SKIP =
GNDS = PGND = GND, VFB = VCSP = VCSN = 1.200V, D0–D6 set for 1.20V (D0–D6 = 0001100). TA = 0°C to +85°C, unless otherwise
specified. Typical values are at TA = +25°C.) (Note 2)
