... Soft Start The EP53F8QI has an internal soft-start circuit that controls the ramp of the output voltage. The control circuitry limits the V levels that are safe for the Power MOSFETS and the integrated inductor. The device has a constant VOUT ramp time. Therefore, the ramp rate will vary with the output voltage setting ...
