TPS61291: CR2450 3volts coin cell battery

Part Number: TPS61291

Hi,

I am using TP61291 to boost the voltage supply of CR2450 from 3V to 3.3V that is use to power up our device with 80mA load. EN pin is directly connected to Vin.

I have similar problem to this post: https://e2e.ti.com/support/power-management/f/196/t/660731

Please kindly advice what would be the perfect selection of capacitors should be use in our design.

It works when 1000uF or 1F Electrolytic capacitor is added in our design otherwise ceramic capacitors would not work.

Thank you.

Kind regards,

Naig
