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 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 it shows up…
Part Number: LMR14203 Tool/software: WEBENCH® Design Tools Hi team,
When I run Webench simulation (Load transient) of LMR14203, it fails to complete the simulation and I got below message.
Could you please confirm that condition?
Condition, VIN=11.8V to…
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 turn…
Hi JP,
I noticed that the junction to ambient for both LMR16006 and LMR14203 are not the same.
LMR16006 = 102 C/W
LMR14203 = 121 C/W
In that case, is it verified that LMR14203 can reference the same reading from LMR16006 for the junction to case?

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 happens…
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.

Other Parts Discussed in Thread: LMR14203 , LMR14206 I question whether the webbench model for the LMR14203 is accurate. it fails when trying to use it for a design which the literature shows as typical. it errors as failing min TOn time. there should be…
Part Number: DAC5311 Other Parts Discussed in Thread: LMR14203
I am designing a power supply for a product that uses the DAC5311.
The power supply uses a switching power supply LMR14203 for efficiency.
The drive voltage of the DAC5311 in normal operation…
Other Parts Discussed in Thread: LMR14203 Hello,
I am using the LMR14203 to charge a buffer of an LED flasher. The buffer is 20x 47uF/16V MLCC capacitor. The supply voltage is 24V and the buffer voltage is 9V. During the LED flash the buffer voltage will…
