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.)
