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℃.…
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,
S…
Hello,
Please tell me how the current limit functions.
In the datasheets, it is merely mentioned that some reference voltage decrement and resulting foldback will occur (shown below).
I want some more detail, because it is a critical informatin…
Other Parts Discussed in Thread: LM20323 , LM20242 , LM20343 What is the minimum controllable on-time for these parts? Datasheet doesn't specify it for any of these. LM20323 datasheet mentions that for on-time <= 200ns operation extra 22pF capacitor should…
Part Number: LM20343EVAL Other Parts Discussed in Thread: LM20343 , LMR33630 , Hello,
I am writing to inquire regarding the maximum allowed output voltage for LM20343 evaluation board. I need to adjust the output voltage using DAC voltage so I need…
Hi Ethan,
Thank you. Equations 1 and 2 in which file? Please I still did not get it. Please bear with me. I have a MCU that will decide a voltage reference that my application should operate one. I need to send it to the LM20343. I still do not know…
Part Number: LM20343EVAL Other Parts Discussed in Thread: LM20343 , TLV62130A For this LM20343 Evaluation Board, what is the minimum input Voltage for a 4.9 volt output under 2.33A load?
I have the LM20343 that not have the Spice Model. You have advised me to use LM20333 to perform simulations but LM20333 always operates at 200 KHz although fits a square wave signal (0V Low - High 2V) with frequency of 1MHz on the SYNC pin.
How can…
thanks a lot Stephen,
a customer is using the part and he is having problems with the nRESET: sometime it works fine, other times doesn't (and got latched, so that a POR is needed)...
attached some waveforms of the main signal:
Channel 1 (yellow…
