Our customer is evaluating LT8302.
He asks theta j-c of LT8302 .
I do not find theta j-c in the datasheet.
If you have its information, please let me know it.
Our customer will use LT8302 fly back and LT8640S.
(24V-> 5.5V by LT8302 and 5.5V-Vf-> 3.3V about 4A by LT8640S.
(Refer to attached slide 1)
He simulated this design by LTspice.
(Result is attached slide 2)
When LT8302 SW current reaches…
thanks to reply me，
1.because I have apply to purchase LT8302，can you tell me why LT8302 cannot provide 1.25A output current at 16Vin?
2.For a proper design, LT8302 outputs 1.06A at 16Vin.---so need change Z1-->CMZ5934B(VZ=18V), and…
I made the same circuit as the LT8302 data sheet p.22 [8V to 36VIN/±12VOUT Isolated Flyback Converter] .
When this was evaluated, the value of cross regulation was as large as 1.5V or more.
Do you have a cross-regulation value…
There are some PSE evaluation boards for higher output power:
I have apply to purchase LT8302and LT8304, please give me some suggestions，I just have reviewd the datasheet of LT8302 ，typical specification :8Vout Iout=0.9A is very close to my design， my design condition： VIN=16~40VDC， vout=8V，Iout=1.25A， please…
Hello, I have a problem with the LT8302 the device creates to much radiation.The following schematic I have used:
I got this report from the testing agency the left graph has the probe horizontal and the right is the test probe vertical:
With no load connected…
LT8301's Vin minimum is 2.7V, does not go negative.
If you are interested in negative input applications, LT8302 datasheet has two such circuits on page 23.
It is best to reduce that spike as much as possible, otherwise, the output voltage regulation is affected. I will limit it within 1V, according to my experience.
10% of peak value is not acceptable. RC snubber helps to damp this spike.
I'm using the LT8302 in a DCDC converter design with the following requirements:
9 - 18V Input0.5 to 2.5V Output, adjustable from primary side via a voltage input0 to 2.5A
I have been successful in varying the output using a potentiometer to achieve…
