Part Number: TPS63020-Q1 Tool/software: Hi,
I'm using the TPS63020-Q1 as a 3.3V buck boost converter for a lithium-ion battery with an input range of 2.6V to 4.1V. This powers a BLE module which, depending on the transmission level spikes between 30…
Part Number: TPS63020-Q1 Other Parts Discussed in Thread: BQ25798 , , TPS63020 , TPS63000 Tool/software: Hello!
We need to obtain 3.3V from a 1S1P Li-Ion battery pack, using a BQ25798 as charger.
The problem is that when the battery is not connected…
Part Number: TPS63020-Q1 Team,
Figure 1 from the datasheet shows the max output current vs. input voltage, but only for T J = 125 °C. Do we have similar graphs, e.g. 60 °C or 85 °C?
Thanks, Robert
Part Number: TPS63020-Q1 Hi,
TPS63020-Q1's datasheet describes 2 kinds of VFB spec in P.5, one is at PS/SYNC = VIN and the another one is at PS/SYNC = GND. Why are the specs defined separately? PLS tell me the reason to separate and the reason why the…
Part Number: TPS63020-Q1 Other Parts Discussed in Thread: TPS63020 I use TPS63020 as a TEC drvier。
I use the Equations in the article SLVA677 to calculate the value of the R1,R2 and R3 。
I want to understand the relationship between the TEC current…
Part Number: TPS63020-Q1 Other Parts Discussed in Thread: TPS63020 Hi,
I read the document http://www.ti.com/lit/ug/slva726/slva726.pdf
In section 3.2 Backup Capacitor Charging Operation, it says that "The TPS63020 buck-boost converter operates bidirectionally…
Part Number: TPS63020-Q1 Hi
I have a simple question.
This device has a average (inductor) current limit in the high side (buck)switch.
So that , we can estimate a current limit as following at each mode,
at Boost : Iave = Eff * Isw * Vin/Vout…
Part Number: TPS63020-Q1 Other Parts Discussed in Thread: TPS63020EVM-487 Hi
Our customer are going to estimate the start up time.
However there are no specification of the delay(startup) time on the datasheet.
How can we estimate the following…
Part Number: TPS63020-Q1 Other Parts Discussed in Thread: TPS63020 Hello,
I have a design that uses two TPS63020's to generate 5V and 3.3V. The units seem to test out fine when I build and bench test them; but my client has had several units "spontaneously…
Other Parts Discussed in Thread: TPS63020-Q1 Hello,
In the datasheet Figure 11~17 of TPS63020-Q1, there are the Load Transient Response, Line Transient Response and Startup After Enable data on the condition of PS/SYNC = High(Power Save Disabled). …
