Part Number: TPS563300 Hi, In the data sheet www.ti.com/.../tps563300.pdf I noticed that the layout example shown in Figure 8-23. TPS563300 Top Layout Example has all 8 pins of the chip connected but two of those pins are labelled NC. Is this correct…
Part Number: TPS563300 Tool/software: Hi,
I am using TPS563300 buck IC in my circuit.
Observed the switching frequency to be lower close to 27~35kHz. But need to increase to 500kHz to reduce the inference.
Request to suggest methods to increase…
Part Number: TPS563300 Hi all,
If I use the above formula and refer to the data sheet values, you can calculate as follows.
The calculation result is R1=517k, R2=87k, which is different from the data sheet values R1=511 k, R2=80.7 k. 1) What is…
Part Number: TPS563300 Hello TI Support Team,
I am currently using the TPS563300DRLR buck converter in my design. However, my application requires a higher output current of around 4.5 A. Could you please suggest a pin-to-pin compatible alternative…
Part Number: TPS563300 Hi Team,
Customer said that there are the differences between their measurement data and the datasheet on the negative voltage of SW pin by load current. Please check the attachment below and let me know the reason why. And please…
Part Number: TPS563300 Tool/software: I am attempting to simulate a simple buck converter in PSpice using a TPS563300. The datasheet indicates that pins NC0 and NC1 must be left floating, and that EN can be left floating. When the aforementioned pins…
Part Number: TPS563300 Tool/software: Hi,
I'm planning to use TPS563300 in my design, where my design's I_max is ~0.9A and I_lpeak is ~1.5A.
But the Datasheet suggests to choose Inductors Satuation Current to be more than High-side switch current…
Part Number: TPS563300 Tool/software: I am trying to simulate a buck 12V to 10V buck converter using the TPS563300 in PSpice. My circuit simulates without error but produced the wrong voltages. I have included the images of a working circuit I was given…
Part Number: TPS563300 Tool/software: Hi Team,
I would like to ask you about VIN and VOUT waveforms under OCP and OVP. I couldn't find the waveforms like the picture below in the datasheet, so please share them with me.
Regards,
