Additionally,
As per my further exploration I found TPS61261
In this datasheet, there is mentioned that it can be used for coin cell batteries.
So i doubt that the minimum switching current of 200mA in tps61221 causing the issue
I honestly do not understand…
Scope waveform of battery not connected to anything:
Battery connected through fuses and diodes to the load:
Input to TPS61261 with fuses and diodes and load:
Output of TPS61261 with fuses and diodes and load:
Input to TPS61261 without fuses and diodes…
Good day,
I am designing a stand alone RFID reader with a TMS3705 and a MSP430G2553, It will read at a distance of 2cm. or one inch every 3 seconds, my idea is to use a TPS61261 for the 3v3 MCU and a TPS60140 for the 5V of the TMS3705, what kind of long…
I split this thread since it is on a different topic.
Yes, the curves in the D/S are measured.
The TPS61025 is more efficient but requires a larger solution size as well as needing ESR in the output cap.
If you have a lower output current, then I recommend…
