Hi Alessandro,
You may contact Coilcraft to get the samples of YA8916-BLD: cust_service@coilcraft.com.
The turns ration 1.1 : 1 is a suggestion and the 1:1 transformer should work.
Regarding the 1nF capacitor across the isolation boundary: It is to contain…
Hi Saivin,
I meant the 2nd configuration. I saw you already have capacitors across the input/output isolation boundary. For the input common mode filter, please try to ground the Y-cap closer to the primary side of the isolation boundary, and see if the…
Part Number: LM5181-Q1 Hi TI Team,
Requesting to provide LM5181-Q1 IC, T C pin input leakage current , which will help in our design. Kind regards, Vamsi Bankuru
Part Number: LM5181DESIGN-CALC 1.can you provide us the design calculations for RC series snubber circuit across the primary winding of transformer?
2.R2 and C12 power loss calculations. Thank you advance, please provide ASAP.
LM5181 Bipolar + and - 18…
Part Number: LM5181 I am working on safety analysis using this IC.
IF the FB pin is shorted to ground then voltage at + terminal(1.21V) of error amplifier will be more than - terminal of error amplifier.
So, output of error amplifier will be high and…
Part Number: LM5181 Hi team,
Could you please help advise -
What is the softstart reference voltage? 0.8V? Customer need to measure the softstart time at SS pin.
What is the switching frequency during softstart and how does it change?
"A failsafe current…
Part Number: LM5181 Hi,
here we want to understand the theory of the secondary current detect.
below we described the BCM mode, we could detect the secondary current to turn on the MOSFET when the current is 0.
could you help to clarify how could our…
Part Number: LM5181 Other Parts Discussed in Thread: LM5180EVM-DUAL Hi,
we have custom board with dual output flyback design based on LM5181 with following parameters:
Vin nom= +12V
Vin range = 11V…13V
Vout1 = +12V /200mA
Vout2 = +56V / 5mA
Npr…
Part Number: LM5181-Q1 Dear team,
I have a question regarding "SAMPLED FEEDBACK" block on the functional block diagrams.
This block is positioning between comparator of Vref and FB-pin.
1. What is the function of this block?
D/S says that PSR…
