Part Number: LM5163 Tool/software: My customers are using LM5163 and are facing some problems of the unstable switching frequency and acoustic noise of inductors. As showed in the schematic, they designed the schematic for a 74Vin (60V-85V), 5Vout, 0…
Part Number: LM5163 Tool/software: Hello Team,
I am using LM5163 in applicaion where we are having 12V input and 10V output with 0.4A Load. I have used Type 3 ripple circuit for this.
Below is the output ripple waveforms with CH2 is buck output (Red…
Part Number: LM5163H-Q1 Other Parts Discussed in Thread: LM5163-Q1 Tool/software: Hello,
I am using the LM5163-Q1 Buck converter in my Motor control unit to generate +12V power supply from 48V input. It is mentioned in the Datasheet that "the value of…
Part Number: LM5163 Tool/software: During load transient of 400mA to 0mA I have observed voltage overshoot approx. 5.5V (0.5V additional for approx 50ms) at output of diode.
My configuration of buck converter is shown in below snap :
The purpose of diode…
Hi David,
David Baba said: They may have added 1Mohm to terminate the pin and not leave it open. in your sim, use 82k.
I used 82.5Kohm for the simulation snip-shot attached
David Baba said: Rboot = 1ohm, Max 5ohm, if needed.
I used 1ohm for the simulation…

Part Number: LM5163 Tool/software: Hi,
We are using a LM5163DDAR in a new design. It is used to generate 5 V / 0.3 A from 20...50 VDC, the schematic looks like this:
Using the values in the schematic the output voltage was not very stable and jumped…
