Part Number: LM5180 Tool/software: Hi. using LM5180 dual out put
Transformer design Nps = 1.2 , Lm = 40uH
Output Voltage = 20V , 0.1A
When Rfb = 300K and Rset = 16K, the output voltage is 20V. Is it possible to change Rset to 12.1K? Will there be any…
Part Number: LM5180 Other Parts Discussed in Thread: LM5185 , LM25180 Tool/software: Hello, TI team
I am studying LM5180/LM5185 for MOSFET gate drive PSU and have some questions troubling me .
Appreciate you could help to clarify it.
1. The Min m agnetizing…
Hi Frank,
1. The Dclamp replaces the usual RCD snubber to cope with the turn-off voltage spike on the internal FET. The voltage rating should be greater than the reflected output voltage, namely Nps x (Vout+VF), then it will not affect Vout.
2. The output…
Part Number: LM5180 Tool/software: Hello,
I am reaching out regarding the use of your WEBENCH Power Designer tool. After generating a power supply design using the online tool, I noticed that in some designs, an input EMI filter is shown. However, no…
Part Number: LM5180 Tool/software: Hello, I'm designing a power supply that will be able to provide high voltage (about 500-600V) low current (on the order of 1-2 mA) AC. I have a working solution, but I'm not satisfied with its footprint and absence…
Part Number: LM5180-Q1 Tool/software: When I try to run a PSPICE simulation for this part, I keep getting an error that there are less than 2 connections at the TC node. I have connected a resistor between the TC and RSET nodes, and in the .CIR file…
Part Number: LM5180 Tool/software: Hi Team,
My customer target to use LM5180 for PSR ISO module, we are wondering why the modes of Operation will show as below logic?
Just like , why using BCM in heavy load and why not DCM working at heavy load?
would…
