Part Number: LMR14203 Hi,
I am running some LMR14203 chips with 40Vin, 28Vout, components as below:
I seem to have some chips that are switching off and restarting during operation (see switch off in scope trace)
I am relatively sure it…
Part Number: LMR14203 Dear
My Japan customer has a question about LMR14203XMKE/NOPB. The question is below:
Please tell me how to output negative power.
1. Is the GND terminal good for connection to GND of VIN?
2. About /SHDN control, when turning…
Part Number: LMR14203 Hi,
my customer is using LMR14203 in following configuration:
Vin: 24V
Vout: 5V
Iout: 0 to 0.3A
When doing a simulation in Webench a accuracy is given of 4.11% without load and when looking into the worst case date…
Part Number: LMR14203 Other Parts Discussed in Thread: LM2841 Hello!
I designed a project that uses the LMR14203 converter. After mounting only the power supply components I noticed that, sometimes, after powering up the circuit, the output is short…
Part Number: LMR14203 Hello,
I have a design with two LMR41203 switchers. Per the pin descriptions on page 2 of the datasheet, I decided to leave the SHDN down floating. However, the switchers are not turning on.
If I apply VIN to the pin, they both…
Part Number: LMR14203 Other Parts Discussed in Thread: LMR16006 , Hello,
Our customer wants to know the thermal resistance value , theta jc for LMR14203XMKM/NOPB, it is not shown in the datasheet.
Could you provide this ?
Thanks and best regards…
Other Parts Discussed in Thread: LMR14203 Our customer has a problem of LMR14203.
Some LMR14203 stops switching.I attached circuit and waveforms.
When they add dammy resistor to output,SW waveform become good.
Please let us know why these phenomenon…
Our customer wants us to provide the temp distribution data of Vfb.
We of course had showed +/-2% at -40~+125C, however he needs a temperature dependency like the following device Fig14 graph.
