DC1886A - LTC4232: 5A Integrated Hot Swap
... Current reaches the initial limit when FB is at zero. Once FB rises above approximately 100mV the current (and hence the output ramp rate) increases, however the timer expires before the output reaches its final value. The correct way to ensure successful power-up into an output capacitance greater ...
