Hi,
I have a timing problem with the EVM3695-20 evaluation board.
When i start up the board i always have a delay of 3.5ms which i cannot change. The TON delay is set to 0ms and I still have a 3.5ms delay between VIN and VOUT as shown in the attached pitcure.
How can I change this behaviour?
Thank you!
Regards,
Kirsty Lehmann
Hello Kirsty,
This 3.5ms delay between Vin and Vout is intentional as the MPM3695-20 includes a power-up sequencing delay for internal bias and protection circuits to stabilize before the output is enabled. This delay is not related to TON_DELAY, which applies after the internal soft-start logic is activated. See the following startup waveform from the EVM3695-20 datasheet below:
