Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: LM20343 Hello,
I built a DC buck converter using LM20343. The components for the converter are identical to those in the evaluation board (LM20343Eval). However, I have a high voltage ripple at the output. I tried to use several capacitors…
Part Number: LM20343 Hello E2E team,
I have a question and I hope you bear with me. I am planning to control the input voltage of LM20343. The only modification is to connect the voltage divider to sense the input voltage, not the output voltage. At the…
Part Number: LM20343 Hi Team,
My customer is using LM20343 for 24Vin_15Vout/2.5A application and they would like to check some parameters in datasheet:
Max Duty Cycle: datasheet shows typical value is 80%, but didn’t shows the Min value, could you help…
Part Number: LM20343EVAL Other Parts Discussed in Thread: LM20343 , LM5170-Q1 , LM5176 I am writing to inquire about the possibility of using the an evaluation board for a synchronous buck converter (Say LM20343Eval or a synchronous buck-boost toology)…
Part Number: LM20343 Other Parts Discussed in Thread: LM5117 I am working on a design where I want a buck converter to operate primarily as a current source, and I am trying to decide the best way to do it. This link was helpful to get me thinking about…
Hi Team,
I'd like to ask about LM20343 webech simulation.
Our customer is going to use LM20343 on the following condition.
◇Vin(typ)=20.5V,Vout=16V,Iout=2.5A
I was able to simulate in webench.
4572.WebenchReportsServlet.pd
Does this simulation result…
Other Parts Discussed in Thread: LM20343 Hi Team,
I'd like to ask about LM20343.
Our customer want to know the max duty cycle.
Please tell me the Min of max duty cycle.
Our customer is going to use LM20343 on the following condition.

Other Parts Discussed in Thread: LM20343 Hi Team,
I'd like to ask about LM20343.
Our customer want to know discharge time of the soft-start capacitor.
Could you tell me the current that flows when the discharge of the soft-start?
Or, Could you tell…
Other Parts Discussed in Thread: LM20343 Power Good of LM24620Y and LM20343 will not use.
At that time, is there a problem to make the PGOOD pin open?
When the GND connection is necessary, what is the problem by PGOOD-open ?
Best regards,
Satoshi
Other Parts Discussed in Thread: LM20343 Hi,
Could you tell me about switching frequency of LM20343?
I think that the switching frequency(Fsw2) value of datasheet is the “225kHz(min) / 250kHz(typ) / 325kHz(max)” at VIN=12 , TA=Tj= -40℃ to 125℃.…
