Part Number: TPS63900 Tool/software: I am using TPS63900 Is Buck Mode. Input Voltage as 4.2V and Output Voltage at 3.3V. Load current as 0.5A. I want to calculate peak current through the I.C. and Inductor and for that I need to know the tw:A; , tw(B…
Part Number: TPS63900 Tool/software: Hello,
In the TPS63900 datasheet TI recommends:
“For correct operation, TI recommends that the total RMS error of the configuration resistors—including initial tolerance, temperature drift, and ageing—is less than…
Part Number: TPS63900 Other Parts Discussed in Thread: TPS63021 Tool/software: Hi,
I recently asked about TPS63021(Enabling PS), but now we are considering to replace it with TPS63900.
We are assuming that it will be used under the following conditions…
Part Number: TPS63900 Tool/software: Hello,
I’m working with the TPS63900 boost converter to charge a 5 F supercapacitor from a 3.6 V input rail up to 4.7 V. The device successfully charges the supercap, but once it reaches the target voltage, the average…
Hi Sukwoon,
Then, it should be no OTP risk. we should focus on other possibility, but for now, i have no idea about what happened in your side.
Do you have EVM on your hand?

Part Number: TPS63900 Tool/software: Hi team,
I have a few questions about Battery Lifetime Estimator. We have selected a lithium ion battery and plan to use inputs to the circuit ranging from 4.2V to 3.0V. On the circuit side, there are 4 main power supply…
Part Number: TPS63900 Tool/software: Hi,
In a battery powered meter application the TPS63900 shall recharge the voltage on a supercap as soon as the voltage drops below 3.6V (so the boost should recharge from 2.5V up to 3.6V).
At the initial instant…
Hi Jasper,
TPS61094 cannot support VSUP discharge down to 0.8V. For boost converters, the supported max Iout can be calculated by:
If you need 0.8V Vin, 3.3V Vout and 1A Iout, you'll need to select a boost with over 4.58A current limit. So we recommend…
