CONSTANT SLOPE CIRCUITS

The RP106x Series is equipped with a constant slope circuit as a soft-start circuit, which allows the output

voltage to start up gradually when the CE is turned on.

The constant slope circuit minimizes the inrush current at the start-up and also prevents the overshoot of the

output voltage.

The capacitor to create the start-up slope is built in the IC that does not require any external components.

The start-up time and the start-up slope angle are fixed inside the IC. For more details, please refer to the

graph 15 of “Inrush Current Characteristics Example”.
