Part Number: LM5117-Q1 Tool/software:
LM5117QPMHX_NOPB gate resistance can be tuned to 9 ohm without compromising working and efficiency of buck
When there is no load connected to LM5117QPMHX_NOPB buck, why there is more emission at 960kHz. What is…
Part Number: LM5117-Q1 Other Parts Discussed in Thread: LM5190 Tool/software: Hello Team,
We are using LM5117-Q1 in one of product. We want to check whether LM5117-Q1 is suitable for Super Capacitor charging application with below specifications:…
Part Number: LM5117-Q1 Other Parts Discussed in Thread: LM5117 Tool/software: Hello I am using LM5117 with switching freq 480KHZin my ECU during Radiated emission in 966KHZ and 160MHZ. When I checked with near field probe I am getting the emissions source…
Part Number: LM5117-Q1
Tool/software:
I am using LM5117PMHX/NOPB IC and following this schematic from LM25117 Evaluation Board .
I designed it for 12V output but I am getting ~2.7V output which is a problem, I have tried few solution but nothing…
Part Number: LM5117-Q1 Tool/software: Hello EricLee
Can you please explain the technical reason to me how each of your recommended steps listed below can help in reducing the emissions.
Make SW node copper area smaller.
Add RC snubber between…
Part Number: LM5117-Q1 Dear team,
I understand that if even a momentary surge is applied to Vin that exceeds the absolute maximum rating, may potentially breaking the device and affect its reliability. But, I would like to confirm the following as the…

Part Number: LM5117-Q1 Other Parts Discussed in Thread: LM5117 Our customer is considering to develop a step-down converter with constant output power control for a new project. TI LM5117 The document at the URL below describes constant power control…
Part Number: LM5117-Q1 Hello,
I have designed a synchronous buck converter using LM5117-Q1. Even after keeping the SW node and power loop very small, I am observing ringing on the SW node with an amplitude of 100V at full load condition of 10A and input…
