Part Number: LM5164 Other Parts Discussed in Thread: LM5163 TINA-010208 as a REFERENCE circuit diagram I designed the circuit diagram of LM5163 and applied LM5164 for the actual parts. The LM5164 is currently experiencing a RINGING phenomenon. What debugging…
Part Number: LM5164
Hi,
We configured the circuit as shown in the schematic above. Out of 10 assembled boards, 2 boards exhibit audible noise coming from the input MLCCs. The PCB artwork was designed according to the reference layout in the datasheet…
Part Number: LM5164-Q1 Hi team,
A PCN notice has been issued for the LM5164-Q1.
Are the recommended thermal pad land patterns the same before and after the PCN?
Since the size of the thermal pad itself will change, should the land pattern be adjusted…
Part Number: LM5164 Tool/software: Hi,
I am using the LM5164 buck converter.
Vin = 48V nominal (30V-57V)
Vout = 10.3V
Iout max = 0.1A
Freq = 250kHz
L = 100uH
When i decrease the load to ~0.3mA i see the following spike in the SW pin:
…
Part Number: LM5164 Tool/software: Hi, I
designed a DC/DC converter using Webench with a 14-100V input and 12V/1A output.
There’s an audible hissing sound (‘tssss’), especially under light load. The circuit works correctly, but I’d like to identify…
Part Number: LM5164 Tool/software: Hello,
I am trying to design a circuit to accept a variable voltage input between 15VDC and 100VDC. I need to convert this to a regulated 12V output to drive a few LEDs and MOSFET gates. The LM5164 was getting very…
Part Number: LM5164 Tool/software: Hi Team,
Customer is testing LM5164 for their project, and they found the empty load waveform looks a bit strange(high ripple), could you please check whether the waveform is correct or not. Thanks.
Application conditions…
