... The control circuitry limits the V safe for the Power MOSFETs and the integrated inductor. The EN5339QI has a constant startup up time which is independent of the VOUT setting. The output rising slew rate is proportional to the output voltage. The startup time is approximately 1.4ms from when the ENABLE is first pulled high until VOUT reaches the regulated voltage level ...

... ENABLE) together during power up or power down meets these requirements. Pre-Bias Start-up The EN5339QI does not support startup into a pre- biased condition. Be sure the output capacitors are not charged or the output of the EN5339QI is not pre-biased when the EN5339QI is first enabled. shutdown September 12, 2012 EN5339QI www ...
