Other Parts Discussed in Thread: TPS61253 Hi all,
I tested the tps61253evm board, input voltage Vin 4V, EN = 1.
At output load Iout smaller than 180mA, Vout was stable at about 5,17V. When I raised Iout to around 300mA, the output voltage Vout fell down…
Is there a min/max oscillator frequency specified or characterized for this part? Under what conditions will the frequency be at either of these extremes?
Thanks in advance.
Hi, Chris
When I replied our conversation, It is disappeared. So. I made new conversation.
Anyway....
Question 1: Finally I want to know that is it OK 1A continuously at 4.5V<Vin<5.5V without thermal fault When I designed with recommended condition…
[Answer for 1st question]
We supply TPS61253 3.3 to 4.2V with the battery. If the battery is full, it can supply 4.2V, and if the battery is almost empty, it supplies 3.3V or less.
[Answer for 2nd question]
We haven't replaced TPS61253 because TPS61253…
Part Number: TPS61253A Other Parts Discussed in Thread: TPS61253 Hello,
I'd like to use this boost converter to provide a 5V supply from a Li-ion battery to a circuit that may also be powered by USB, but I can't tell from the the block diagram if there…

thanks for your prompt answer, to avoid the scenario, i.e. system restart, i would like to choose your recommendation as using different interface between bq51050B, the battery and the TPS61253. but considering TPS61253 only has one VIN pin, how to achieve…
in the li-ion input voltage application, i would suggest TPS61230 instead of TPS61030. I guess the input current will not higher than 1A, so you can have a look at TPS61253 series or TPS61252.
thanks
