Part Number: TPS54240 Other Parts Discussed in Thread: TPS54340 , TPS54341 Tool/software: WEBENCH® Design Tools Dear Sirs,
We used TPS54240 DC/DC converter in our old design. It has a good cost and is widely used us. Our design contains two power supplies…
Part Number: TPS54240-Q1 Hi all,
I don’t see the marked input/output voltage difference in the data sheet; I want to confirm how to determine that I want to output 3.3V and how many volts should I input at the lowest VIN? The current load is 1.5A, thank…
Part Number: TPS54240 Hi,
After being exposed to multiple load dump transient pulses (58V/250ms / Pulse 5b - ISO7637-2), the buck converter (TPS54240), which has been rated for maximum 47V, is still operating without any defects. In addition, we also …
Part Number: TPS54240 I confirming about external clock circuit on TPS54240, please let me confirm about two points below;
・Circuit image is attached below, is this no problem?
I'm little worry about RT/CLK pin voltage, 10pF coupling occur negative voltage…
Part Number: TPS54240-Q1 Other Parts Discussed in Thread: TPS54240 , Hello,
I am designing a power supply using TPS54240-Q1 with 28 V nominal input voltage and 10 V output voltage. I used WEBENCH to design my circuit at first, however, solution size is…
Part Number: TPS54240 Hi Team,
I have a question about TPS54240 split rail power supply short circuit behavior.
My customer concern is following 3 cases. 1. VOPOS shorts to GND 2. VONEG shorts to GND 3. VOPOS/VONEG shorts to GND
could you let me know how…
Part Number: Hello. I am using TPS54240 to convert from 12V to 5V. A connector is attached to the 12V side, and when this connector is repeatedly inserted and removed hundreds of times, a spike voltage close to 12V may rarely appear at the 5V output from…
Part Number: TPS54240 Application note of slva540: inverting buck-boost is described below RT/CLK condition.
Please let me know about two points below;
・Required time for RT/CLK: high timing after power up (= EN: high).
・If RT/CLK held high during power…
Part Number: TPS54240 We used 3pcs TPS54240 for 20Vdc&12Vdc&5Vdc output, the same power input (28~40Vdc), schematics and layout.
The output waveform 20Vdc &12Vdc is nonlinear while power on/off , but 5Vdc is ok.
Any solution to improve the…
Part Number: TPS54240-Q1 Dear team,
Customer would like to design 12~24Vin to 12Vout/2A in automotive application. I found TPS54240-Q1 which can operate in 100% duty-on.
I would like to double confirm with you the output voltage drop in 12Vin to 12Vout…
