Part Number: LM34925 Other Parts Discussed in Thread: LM34926 , , LM5018 , LM5019
Hi Team, Is Buck Switch RDS(ON) same between LM34925 and LM34926 under same test condition? The datasheet shows the value is the same however test condition is different as…
Part Number: LM5018EVAL Other Parts Discussed in Thread: LM5018 Dear all,
I was testing the LM5018 Evaluation board and realized a voltage glitch at the output while the output voltage is rising to steady value at start. Corresponding voltage glitch is…
Part Number: LM5161-Q1 Other Parts Discussed in Thread: LM53635-Q1 , LM5018 , LM25141-Q1 , LM53603-Q1 Hi,
We got a question from the customer about LM5161-Q1. Could you help us?
[Question] According to the datasheet, the operating lifetime is de-rated for…
Part Number: TPS55010 Other Parts Discussed in Thread: TINA-TI , LM5018 , UCC2891 Dear support member,
As previous Post locked, I new post.
My customer used TPS55010.
I would like to analyze a two output flyback converter, Could you teach me how to TINA-TI…
LM5017 datasheet typical current limit is 1A. Therefore I think it is to be expected that the short circuit current can be ~1A typically (minus some ripple).
LM5017 family has LM5018/19 that have lower current limit. But again there is no intentional…
Hi Vijay,
I am planning to use LM5018 for an on-board power supply design. But the transformer I want to use with it has very low primary inductance 3.8uH. Do you know what 3 secondary winding transformer would be suitable for this IC? or can you recommend…
Hi Denis,
LM5017 / LM5018 / LM5019 family of parts (100V) can be used to generate +/- voltages in Fly-Buck configuration. The primary side can be positive (like a buck converter) or negative (inverting buck-boost). See the following links for more information…
Hello David,
Thank you so much for yout reply.
When using the LM5018 to generate -36V from 48V, how should I connect the RTN pin
Is the current limit still 300mA in this mode?
Do you know where I can find a reference design like simulation file in TINA…
The LM5018 looked like the best candidate because I have no control over the input voltage, which is dependent on the line voltage and varies quite a bit.
I ran the WEBENCH(R) tool for the LM5018 with:
VinMin= 20.0V
VinMax=70.0V
Vout = 18.0 V
Iout=0.…
Hi,
The secondary regulation (VCC+ in this case) requires that the part be in CCM (continuous conduction mode). This means that the inductor current (primary winding) should be continouous (you should check this on osc). This only happens in a non-synchronous…
