Start-Up Characteristic
The module can be started by applying input voltage
first, then using the control pin to turn the module on, or
by applying input voltage with the control pin in the “on”
state. It is recommend to apply input, then turn the
module on with the control pin for the best start up
characteristics, especially when used at operating
ambient temperature of –40 °C. The following figures
demonstrate the start-up characteristic of each module
into the maximum load. Each converter is shown with
an input ramp of 1 ms and 20 ms
