ELECTRICAL CHARACTERISTICS (continued)
(VIN = 5.5V to 23V or VIN = VREG = 4.5V to 5.5V, VDREG_ = VREG, VPGND_ = VSYNC = VPHASE = VSEL = 0V, CREG = 2.2µF, RRT =
100kΩ, CCT = 0.1µF, RILIM_ = 60kΩ, TA = TJ = -40°C to +125°C, unless otherwise noted. Typical values are at VIN = 12V and TA = TJ
= +25°C, unless otherwise noted.) (Note 1)
