Maxim Integrated 

Dual-Output, 3-/2-/1-Phase + 2-/1-Phase

Quick-PWM Controllers for VR12/IMVP7

ELECTRICAL CHARACTERISTICS (continued)

(Circuit of Figure 1. 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.)
