Figure 5-39 is a 1-A version of the Fig. 5-36 circuit. Figure 5-40 shows the waveforms for a 10-V negative input step (trace A) with a 10-Ω, load. The amplifier responds (trace B) driving the booster to close the loop. The booster output, lagging by nanoseconds (trace C), drives the load with only minor peaking (which can be minimized with the feedback capacitance trimmer). LINEAR TECHNOLOGY, APPLICATION NOTE 47, P. 47.
