Part Number: TPS799-Q1 We need to know VRM Equivalent inductance for TPS79901QDRVRQ1 to set low frequency limit for Decoupling analysis to ensure power integrity. Please provide the VRM Equivalent inductance for TPS79901QDRVRQ1 as soon as possible.
Part Number: TPS799-Q1 I would like to confirm the cause of the unexpected output in EN low for TPS799-Q1.
I attached the waveform.
The conditon is VIN = 3.3V, EN = 2.7V, input capacitor 4.7uF and output capacitor 2.2uF.
The output voltage in EN low…
Part Number: TPS799-Q1 Hi Team
Please help to confirm the maximum capacitor for TPS79933-Q1, in Datasheet it only state the minimum capacitor 2.2uF. thanks.
Hi Charlie,
Thank you for reaching out.
Can you share your schematics?
This is a known problem for TPS799, and i t seems like this issue is related to the Vin rise time and/or load.
