2. Input Undervoltage Shutdown and Start Up Threshold Under normal start up conditions devices will not begin to regulate until the ramping up input voltage exceeds the Start Up Threshold Voltage Once operating devices will not turn off until the input voltage drops below the Undervoltage Shutdown limit Subsequent re start will not occur until the input is brought back up to the Start Up Threshold This built in hysteresis prevents any unstable on off situations from occurring at a single input voltage Start Up Time The Vin to Vout Start Up Time is the interval of time between the point at which the ramping input voltage crosses the Start Up Threshold and the fully loaded output voltage enters and remains within its specified accuracy band Actual measured times will vary with input source impedance external input output capacitance and load The UHE Series implements a soft start circuit that limits the duty cycle of its PWM controller at power up thereby limiting the input inrush current The On Off Control to Vour start up time assumes the converter has its nominal input voltage applied but is turned off via the On Off Control pin The specification defines the interval between the point at which the con verter is turned on and the fully loaded output voltage enters and remains within its specified accuracy band Similar to the Vin to Vout start up the On Off Control to Vout start up time is also governed by the internal soft start
