Hello,
I use TPS63002 and I don't understand how to configure the low-pass filter (100 ohms and 100nF) on VinA, EN and PS/SYNC. Is it possible to remove it ?
In fact, I use a low power input which is 20V input with a series resistor of 180 ohms to go to Vin, which rises slowly due to a big input capacitor (several mF).
The problem I can see is that there is no current enough to start correctly the Buck-Boost.
If I check the output, I can see that there is 1.52V in stead of 5V.
If I increase a little bit the input current, I can see that 5V appears on the output.
I think that the high input series resistor is disturbing the EN pin.
Is there a possibility to change the value of this low-pass filter to avoid this enabling/disabling permanently at low current ?
Maybe there is a calculation with the Undervoltage lockout threshold ?
Thank you for your help.
