Part Number: LM5141 Other Parts Discussed in Thread: LM5115 Tool/software: Hi
Does the LM5141 utilize a different design/layout/die compared to the LM5115?
Thanks,
Vernon
Part Number: LM5115 Other Parts Discussed in Thread: LM25115 , LM5155 I need SPICE model of LM5115. Does anyone have the LM5115 SPICE model? Thank you so much
Part Number: LM5115 Other Parts Discussed in Thread: LM5145 Hi TI
We want to design a non-isolated power supply.
Input is 12-48V, output is 1.0V/10A. Is LM5115 feasible?
Is the frequency of LM5115 fixed and how to set it?
Thank you
Jerry
Part Number: LM5115 Hi TI
LM5115 does not have enable pin, if I want to turn off the output due to protection requirements.
Whether VCC power can only be turned off, or there are other ways?
Thanks.
Jerry
Hi Andy,
1. We will try with 390 pF for the RAMP cap, C4 in the LM5115 datasheet schematic
2. I checked again with my customer to make sure, and our C7 value is 22 nF. I used a MathCAD model I got from David Baba to design the control loop. According…
Part Number: LM5115 Hi
We want to use LM5115 to design a 12V input , 3.3V/8A and 1.0V/8A output power.
Reference specification design, three 0.012 ohm resistors are used in parallel.
Is there a calculation method of current sense resistor?
Thanks…
Part Number: LM5115 Dear E2E,
I've built an SSPR with this controller, and it works well. But the control loop bandwidth is quite low, only around 1 kHz. The device itself has a novel mix of voltage mode, VIN feed-forward and current mode control. Do…
Part Number: LM5115 Dear E2E,
With the help of the small signal model from David Baba I was able to improve the bandwidth and the DC gain of my SSPR using the LM5115. Since the power stage response is mostly a steady -20 dB/dec slope from low frequency…
Other Parts Discussed in Thread: LM5115 , LM25115 , TINA-TI I require a SPICE model for an LM5115 to use within TINA-TI V9. I've found a PSPICE model for an LM25115 which is similar, but I am unable to import it into TINA-TI as the PSPICE .lib file is…
