Hi Support team
We're evaluating LTC3124 internal soft start duration of 10ms.
We observed 12ms time at room temperature.(see below)
How long is this time variation expected?And What are the dominant factors for variation?We know it does not depend on the output capacitor or output voltage from the data sheet.
The start up time is not tested in the auto testing program, so it is not guaranteed. The start up is controlled by the internal circuitry. The silicon varies with temperature, process, etc.
Thank you for your reply.
Is 12msec reasonable value?
Our system cares about the maximum/minimum startup time.
Please provide a reference max/min value as it does not have to be guaranteed.
12ms is a reasonable value. A typical soft-start waveform is on page 4 of datasheet. A good reference value may be 10 to 14ms.
Use this value as a reference.
