Hi Philip,
You're welcome!
Yeah that inductor may make sense with that device's internal compensation. However with the LMR51430 because of its internal compensation parameters and design, you are able to utilize a much smaller LC combination to provide…

Hey team,
I've to 2 doubts that I need clarity on:
1). If I remove the Input Inductor and filtering capacitor leaving only a 4.7uF(C4) and 100uF(C3) polarized capacitor for a 1A load, and reduce…
Part Number: LMR51430 Other Parts Discussed in Thread: LV14340 , LMR14030 Tool/software: Hi team,
my customer wants to find a buck with Vin:24V, Vo:5V and the peak output current is 3A. The load is the encoder part whose maximum Vin is 5.5V which means…
Part Number: LMR51430 Other Parts Discussed in Thread: LM2576 Tool/software: Problem: The board I came up with seems to just follow the input voltage, except less about half a volt - very strange!
Trying to create a relatively simple fixed 12V (automotive…
Part Number: LMR51430 Tool/software: I would like to control my LMR51430 with a digital potentiometer for example a mcp4132 or mcp41010 (1mA max potentiometer current)
output voltage is adjustable between 5 and 20V max current 3A
input voltage 24V
what…
Part Number: LMR51430 Tool/software: Hi team,
I think that the device starts or stops switching after the voltage on the EN pin reaches the EN voltage rising/falling threshold.
How long is the delay time during this period?
Do you have any data on…
Part Number: LMR51430 Tool/software: Hi,
LMR51430 has the frequency foldback function, and it will work when tON_MIN or tOFF_MIN is triggered. Are there any other considerable situations that could be factors of occurring frequency foldback? (except…

Hi team,
Could you tell me about my colleague Go’s question from the other day?
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
My custumor is designing a circuit to convert DC 24V to 3.3V using the LMR51430XFDDCR…
Victory! Some changes to the circuit diagram: Instead of a 22uF ceramic, now using a 22uF wound aluminum (intentionally higher ESR), plus a 4.7uF ceramic on the 12V input. Added a 100nF on the input side, directly next to the input pin. Added a diode…

Hi there,
Found and resolved the issue. It was related to the LDOs, which was having a knock on effect on the LMR51430. Sorry for doubting the switcher! It is working very well now. Please delete this thread.
