A ≥100nF BIAS capacitor should be fine. However, bench verification is indispensable.
I would like to implement UVLO with resistor divider connected to Vin. This looks simple.
But in lt8315 datasheet , (section Protection from Shorted Output Conditions) looks like you use UVLO connected to tertiarywinding, to protect from shorted conditions…

Inductor Voltage rating :400v

Again IC failed with same burnt mark after replacing standard inductor…
I am using LT8315 as a non-isolated buck converter. The input range is 200-400V, the output is 12V 100mA (max)
LTspice simulation shows ok in the input range 30V-400V with static load 120mA.
But actually it works from 30V up to 200V and the…
I used for calculation whole oscillation time, for cdrain it is OK because in equation we use ratio between Tring(snubbed)/Tring. For Leak I should use time only one "sinusoid", not whole oscilation time. Than is OK
I am trying to simulate non isolated buck converter with LT8315 ic given in datasheet as application example of LT8315 in LTspice software. the output is not regulated and does not give 12 volts as per given design . could you please tell what could…
Hi,I am using the LT8315 with the transformer 750316022 as the datasheet sugest.I want to know if I can split the output to get 2 isolated outputs.Vin = 120V
The circuit is very noisy and I want to identify why.
That is similar to the standard evaluate board. The phase margin is >50 degrees.
You can measure the phase margin using FRA on a real board, but you need to use differential probes.
I look for a solution with LT8315: up to 310Vac with 5V output.
Can I use LT8315 for that purpose? Many reference designs are for 12V and above.
We are evaluating the circuit on page 9.
And I'm trying to do an open/short test for each pin.
Are there any points that may cause smoke or fire in this application example?
