Part Number: LM51581-Q1 Tool/software: In the LM51581-Q1 boost converter design application note, how was the inductor RMS current calculated as 3.6 A? Also, the minimum output capacitance Cout_minC_{\text{out\_min}} C out_min was calculated to be 3…
Part Number: LM51581-Q1 Other Parts Discussed in Thread: LM51581 , LMR38025 HI,
Can LM51581-Q1 output negative voltage and is there a solution design? The customer's requirement is to have an input of 12V, an output of -36V, and a current of…
Part Number: LM51581-Q1 Other Parts Discussed in Thread: LM5158 Hi.
We need to simulate the boost converter application using LM51581-Q1 and I could only find the encrypted PSPICE transient model of the same in TI's website. It's an immediate requirement…
Part Number: LM51581-Q1 Other Parts Discussed in Thread: LM51581 I remade the PCB, but the problem still exists，When Input voltage is 12V，input current is 62mA，Its still very high。the SW node wave is below，Fs=2.2M。
It looks like do not input pulse…
Part Number: LM51581-Q1 Tool/software: What is the correct simulation tool to use for the LM5158x models? I currently have available to me LTspice (latest version) and Mixed Signal Simulation in Altium, which can import many different projects/vendors…
Part Number: LM51581-Q1 Tool/software: I would like to have a design provision for a snubber circuit on the switching node. To especially determine the power rating and size of components, one key factor is the switch output capacitance. This is not listed…
Part Number: LM51581-Q1 Tool/software: Hello Experts, https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1468092/lm51581-q1-flyback-design-works-in-simulation-but-not-in-real This above thread explains my previous…
Hi Naveen,
The schematic seems to be ok.
You can also send me your layout to check. I think the debugging makes only sense when you have the circuit on a PCB.
Thanks for sharing the breadboard, but i think with this setup it is not possible to get…
Part Number: LM51581-Q1 Other Parts Discussed in Thread: LM51581 , LM5158 Tool/software: I am designing a boost converter with the LM51518-Q1 and have worked through the design process using Webench and the Excel tool, and simulation to define values…
