Part Number: TPS61378-Q1 Hi TI Team,
Please find below screen shot of boost IC TPS61378QWRTERQ1 Hiccup mode condition waveform.
In this waveform we apply 2.5A overload current (5.5E Load), we found in first waveform 140ms and second 204ms time duration…
Part Number: TPS61378-Q1 Team,
Can you help clarify worst case Pgood set and trip points for the TPS61378?
1. In the datasheet I see that Pgood sets at 90% but then has a 5% hysterisis. Does this mean after Pgood is high we need to be at 85% to drop low…
Part Number: TPS61378-Q1 Hello Expert, I'm customer is designing circuit using this IC. Then, they want to know about the behavior of hicup timer when OC event is removed during short protection.
Does hicup timer's count is cleared immediately to 0ms…
Part Number: TPS61378-Q1 Hi Expert,
My customer is using TPS61378-Q1 in their project. We found a wired phenomenon when short FB pin to GND and remove short. Please see the description as below.
You can find the schematic and test waveform as below.

Part Number: TPS61378-Q1
Hello, I'm using TPS61378-Q1 to get 6V from 3,7V. The device works good, it outputs 6V but when I add a load (6V DC motor), the output falls.
The schematic I'm using is the following:
U3 is another regulator, but it is…
Part Number: TPS61378-Q1 Other Parts Discussed in Thread: TPS55288 Please help fix problem with TPS61378-Q1 . I want to get 2A output current 12.5 V , when input is 9...14V I designed this circuit. R(comp) = 82K C(comp) = 0.001uF **** L = 2.2uH () **** calculated…
Part Number: TPS61378-Q1 Hello, Experts,
We have question about inductor selection. There is a recommendation of running 800mA ~ 2A ΔIL (datasheet 9.2.2.4), but does this include variation in the switching frequency? If we calculate using the max…
