The IC provides accurate load-line characteristic. The regulator can be programmed to lower its output voltage linearly with increasing load current, so that the power generated by the load can be significantly reduced. Since the error in the output voltage directly sets the inductor currents, the dynamic response to a large and fast load transient is close to a square wave. This is optimal for meeting CPU supply voltage specifications. Due to the intrinsic input voltage feed forward characteristic of a peak current-mode controller, the IC has a superior line transient response. |
