Part Number: LM5119 Hi Qian,
Are there any known issues with DCM when using the LM5119 in interleaved mode (single output)?
I am seeing multiple LM5119 failures at > 40V input voltage / no load on the output with DCM, but in CCM this problem seems to…
Part Number: LM5119 Hi.
I have some noise present on the CS and CSG pins of an LM5119 due to adjacent circuitry (another LM5119) switching at inconvenient moments. They are synchronised, so it happens rather predictably.
Adding a 1nF / 100R / 100R differential…
Hi Experts,
Have you measured the TI LM5119 original EVM phase 1& 2 current waveform before with interleaved single output mode ?
I have checked the phase 1 & 2 current & pwm waveform ,it happened the same issue (current unbalance at all load) on…
Part Number: LM5119 I have an LM5119 based design, with interleaved operation (single output). The output is well regulated and stable and the switching waveforms look good. However, I notice that that side 2 of the converter stops switching when the…
Part Number: LM5143 Other Parts Discussed in Thread: PMP31210 , LM5119 , LM5148 , LM5146 , LM5145 Hi, do you know why the LM5143 (Synch Buck controller) was used for this Synch Buck spec (PMP31210 ref design) of 20-58vin and 13.5Vout and 50A out?... PMP31210…
Part Number: LM5119 What is the withstand voltage of the RAMP pin of the LM5119?
In addition,what is the risk if the RAMP pin is connected to VIN via RC?
Part Number: LM5119 When the output of LM5119 is no load, the input power consumption is especially large, up to about 4W.What's the reason? Should the resistance between IC VIN pin and +48V be increased? When the input is 48V, the resistance between…
Part Number: LM5119 When the output of LM5119 is idle, the input power consumption is too large (0.1a 48V). What is the reason for this? We made the products according to the attached schematic diagram 48 v input Output 8 a 42 v When the output is 0 load,…
