Power architects engaged in designing systems requiring low output noise and fast transient response — such as RF transmitters, power amplifiers, test systems, displays, designs supporting low-voltage ...

Figure 1 presents the block diagram of the control loop, which has been greatly simplified. In the left block, the error amplifier is represented by an integrator ...

Thanks to a pseudo-fixed-frequency architecture, the AAT1130, a 500-mA monolithic step-down converter, offers transient response that’s said to be at least twice as fast as a traditional 500-mA, 2-MHz ...
