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 = 0°C to +85°C, unless otherwise noted. Typical values are at TA = +25NC. All devices
100% tested at TA = +25NC. Limits over temperature guaranteed by design.)
