Part Number: LM5117-Q1 Other Parts Discussed in Thread: LMV431 , LM5117 I plan to implement a CC/CV regulator very similar to Figure 3 in SNVA829. One thing that I am concerned about is the absolute maximum voltage on the FB pin. From the Figure 3 schematic…

Hi,
I'm reading the SNVA829. In the section 4 of this doc, it says the Rsense in series with the output will increase the loss. But when using a Rs to sense the output current, it will also increase the loss, right? As shown in…

Hi, I'm using LM5117 to output 25W constant power.
If I use E-load to simulate a constant resistor load. After a period of time, I hear some noises from inductor (inductor whistling), and output gradually reduces to 0V and 0A…
Part Number: LM5117-Q1 Other Parts Discussed in Thread: CSD19537Q3 , LM5116 Attached are the simulation files (not sure if it is attached properly!)
Could any one help with fixing this convergence error! I have tried multiple tweaks tp get my synchronous…

Part Number: LM5117 Hi, I plan to use the DAC to provide real-time feedback to LM5117 buck IC. Therefore, I would control Vout in real time. Has oneone did this succesfully before? Could LM5117 support DAC feedback?
In my circuit, if I use classic resistor…
Part Number: LM5117 Hi, TI team
I'm using DAC to provide feedback and control LM5117 output voltage. Load is purely resistive.
From the TI Excel LM5117 simulation tool, using external VCC will reduce the heat disspation of the LM5117 buck. Therefore…
Part Number: LM5117 Other Parts Discussed in Thread: LM25148-Q1 , LM25149 Dear Sir/Madam
Can I get same specification IC (Current and voltage controlled mode) with duty cycle more than 90%.
Currently we used : LM5117PMHE/NOPB
Please suggest me the alternate…
Part Number: LM5117 Hi, TI team
I'm using LM5117PMH/NOPB to provide DC output + purely resistive load + DAC as the feedback control. From the datasheet, I found the current monitor pin formula.
I simplified (I_peak + I_valley) to (2 * I_average_out…
