Part Number: LM5163-LM5164DESIGN-CALC Other Parts Discussed in Thread: LM5164 Tool/software: This is the simulation result of LM5164 you provided. It doesn't seem to be outputting, how do I check the simulation results?
Part Number: LM5163-LM5164DESIGN-CALC Other Parts Discussed in Thread: LM5164 Hi team,
It's a customer issue that I use the quickstart tool to analysis the efficiency of LM5164 at Vin=12V, Vo=5V, Io=50mA .
Other parameters remain unchanged, change…
Hi Kevin,
What is the output current and desired switching frequency? Please fill the quick-start calculator and get back to us.

Hi David
What is the input voltage and load current?
Note that there is no ripple injection circuit in the schematic. Would recommend going through the datasheet in details.
Also 4.7uF 25V output capacitors might not be sufficient, because of derating…
Part Number: LM5163 Other Parts Discussed in Thread: LM5164 , , Tool/software: Dear Sir
Could you help double confirm WEBENCH® POWER DESIGNER LM5163/LM5164 frequency setting?
326kHz --> calculation result 38.3k
Btw, LM5163-LM5164DESIGN-CALC…
Hi G Karthik,
The device should work fine until the peak inductor current is below the min OCP threshold of the device. You have to choose Inductor and switching frequency such that the peak inductor is always below the min.OCP threshold at max load…
Hi Zhanjia
It should be "lesser than or equals to" as per Equation 9 for COT devices.
You may want to go through Selecting an Ideal Ripple Generation Network for Your COT Buck Converter (Rev. A) {Eq 9} for more details. here is the excerpt from the…
Hello Fabio,
please can you fill out the quick start calculator with your requirements so I can check your design against it, thanks.

Hui Kevin,
here are few comments on the LM5164 part of the schematic
For a typical vin (47V) and given circuit parameters, it is required to use RA=150k ~220kohm range for sufficient ripple at FB node
Please directly connect the EP and GND…
