Part Number: PMP4448
Dear Support Team
Today I was testing our first Design with TPS92314. Our design is more or less a copy of PMP4448.
Now I'm trying to optimzie the turn-on delay (A long start-up time gives a sensor light the impression of a reduced detection range.)
What is the optimum/limits for capacitor size at VCC (PMP4448: C4 low as possible) and pull-up to Vin (PMP4448: R6 and R7, high as possible). Or are there any other ways to start the TPS faster?
Our input voltage requirements are 100 to 240VAC, and it seems only that only the startup delay at 100VAC is too long (>2s) and should be < 500ms.
Thank you for your support.
