Soft-Start

The MA2004A includes a soft-start timer that limits the voltage at the error amplifier

output during startup to prevent excessive current at the input. This prevents premature

termination of the source voltage at startup due to inrush current. This also limits the

inductor current at startup, forcing the input current to rise slowly to the amount required to

regulate the output voltage during soft-start.
