Dual-Output, 3-/2-/1-Phase + 2-/1-Phase
Quick-PWM Controllers for VR12/IMVP7
ELECTRICAL CHARACTERISTICS (continued)
(Circuits of Figures 1 and 2. VIN = 10V, VCC = VDDA = VDDB = 5V, EN = VCC, VGNDS_ = 0V, VFB_ = VCSP_AVE = VCSP_ = VCSN_ =
1V; [SerialVID = 1.00, FPWM MODE]; TA = -40°C to +105°C, unless otherwise noted. Specifications to -40NC and +105NC are guar-
anteed by design, not production tested.)
