Part Number: LM5190 Hello everyone, I am using LM5190 as buck to convert 60V to 53V but a problem i am facing is that VCC is not giving 7.5V as expected instead it gives 1.3V. I have tied Bias to PGND using a 10k and giving 12V to both VIN and EN and…
Part Number: LM5190 Hi .,
I have designed a buck converter using LM5190.,
Input 57V output 54V.
But whenever i power up., Output voltage is latched to 3.54V.
Kindly suggest on the same.,
Part Number: LM5190 Other Parts Discussed in Thread: UCC27282 Hi everyone,
I am designing a synchronous buck converter stepping down 60V to 53V using the LM5190 controller . To handle high-voltage transients/surges that exceed the pin limits of the…
Part Number: LM5190 Hello, everyone. We would like to use a 0–10 V input to regulate the output voltage of the LM5190 from 10–64 V. Is there an application note for this application? Is there a recommended circuit? Thank you very much, Roger F.
Part Number: LM5190 Hello, everyone.
We would like to use the LM5190 as a pure buck regulator.
VIN = 74V VOUT = 10–64V controlled via FB.
Can we omit the current measurement via the shunt? Can we omit the low-side MOSFETs? With a reverse-bias diode…
Part Number: LM5190-Q1 Other Parts Discussed in Thread: LM5190 I did a design based the LM5190 EVM and neither the EVM or my design can transition correctly into Constant-Current (CC) mode at 8A or above. Instead, both designs at max Iout begin modulating…
Part Number: LM5190 Is it possible to use this for constant current control of a high voltage? Looking to limit ~80v to 75v but mostly just want to limit current to 2a or less. I had looked through the TI power designer and it would only give me options…
Part Number: LM5190-Q1 Other Parts Discussed in Thread: LM5190 Hello,
We're considering the LM5190 for a design. Do y'all have recommendations or guidelines on how to interleave n>=2 of these ICs? I.e. by doing the following for n=2:
Setting FB…
Part Number: LM5190-Q1 Other Parts Discussed in Thread: LM5190 Hello TI team,
I am working on a design with 48 V input and output of 5 V at 3.5 A using LM5190-Q1. However, I could not find any formulas or calculation guidelines in the LM5190‑Q1 datasheet…
Part Number: LM5190 Hello guys,
One of my customers is interested in LM5190.
They wonder if LM5190 can be used as LED driver. I think the device can be used.
Is this correct?
Could you please give me your reply?
Best regards, Kazuya.
