Part Number: LM25116 Battery-powered design, 2S Li-ion input (6.3 to 8.4 V, 7.4 V nominal), 5.16 V output, driving six 64x64 LED matrix panels plus a Raspberry Pi CM4.
KEY VALUES Fsw 149 kHz (RT = 22.1 kohm). L1 = 6.8 uH (Sunlord MWSA1205S-6R8MT, Isat…
Part Number: LM25116 Tool/software: Hi,
I am having some trouble with my LM25116 buck converter design.I have two LM25116 ICs on my PCB. Both of them need to be able to handle an input range of 25V - 33V2. One of them has an output voltage of 24V with…
Part Number: LM25116 Other Parts Discussed in Thread: CSD18540Q5B Tool/software: In the datasheet, it was mentioned that "When running diode emulation mode, the maximum ripple current must be less than twice the minimum load current."
Does that mean…
Part Number: LM25116 Hi,
We use the LM25116 to make -15V from a 20V USB-C voltage input, the design was taken from Webench and does work. However, even without a load the device heats up significantly.
When powering the device we measure a 0.2A current…

Part Number: LM25116 I have received the following inquiry from a customer regarding the explanation of "Values greater than 10ohms must be avoided so as not to interfere with the adaptive gate drive.",written in section "6.3.8" on page 19 of the data…
Part Number: LM25116 Tool/software: Dear Engineers,
I want to design a variable output DC-DC converter to convert 12V to -1V to -20V at 4A , the base on the power design Wenbench , I got the following schematic:
The I want to do a simulation…
Part Number: LM25116 I would like to design a buck converter using the LM25116, but I am not entirely clear about the role of the VOUT pin in output regulation beyond the FB pin.
In my design, I am considering two mounting variants. In the first one…
Part Number: LM25116 Tool/software: Dear Sir/Madam,
I am currently using a LM25116 to recieve voltage from an automtoive main battery (8V to 32V) and outptut a 5V supply (3 Amp max current).
The circuit works fine in our intended 8V to 32V input range…
Part Number: LM25116 Tool/software: Dear Team,
I am using the LM25116 to convert a 24V to -15.00V @ 6A. I used the WeBench for the design my board, but the regulation doesn't start.
I have one question, about the EP pad, does it has to be connected…
