Hello,
I'm currently developing a medical device using the ADS1299, as it needs both a 3.3V and a 5V sources I'm using the TLV61220 to boost the 3.3V to 5V, in principle it works fine and I had some issues when connecting the load, then it started working fine but only for a limited time.
The TLV61220 boosts fine for around a couple of hours and then it stops working, my initial FB voltage is a bit over 500mV and then it drops to around 300mV. Then it remains like this for a couple of days and starts working again.
Any recomendations? I want to use at least 3 ADS1299 chips for my application but I'm not sure if a single TLV61220 give enough power for all of them.
Thanks in advance and regards.
