Hi Yusuf,
There are no output seen in your simulation since the VIN pins are connected by the VIN signal and connected directly with a capacitor which in turn blocks the DC input coming from the supply. for input filtering, connect the capacitor in parallel…
Hi ADIExpert
I am using LTC3862 to implement a boost converter with 12Vin/54Vout 3A with two phase operation
however, they is a sku that may only need 54out/1.5A so I would like to keep using LTC3862 but with only single phase opeartion
May I know what…
i have designed a LTC3862 solution, designed output voltage is 107V/1.5A , and the circuit is same as LTC3862 datasheet parts 107V out circuit. but when measure the output points, it has not 107V , and i change the feedback resistor is not work , the feedback…
我有设计一个以 LTC3862-1 为核心的DCDC转换板，设计输出是107V的电压，电路是手册的事例电路。但是发现反馈点电压 Vfb 只有0.8V， 无论怎么调节反馈电阻反馈电压都不变话，ITH 电压是2.7V， 但是如果我调节负载（调节范围从 90欧姆至100欧姆）的话输出电压会变化，反馈电压也会随着变化。 是什么原因导致了输出会随负载变化， 是什么原因导致了反馈电压不为1.223V，且不可调， 谁能解释一下吗？ 谢谢。
Hello Everyone,
I am going to design step up DC-DC converter using LTC3862 but my output voltage is not fixed and i want to vary it using microcontroller. But i could not find any pin in datasheet to control the output voltage except FB pin.
I don't know…
Hello everyone.
I want to operate CV/CC using an external error amplifier on the LT3862-1.
The output of the external error amplifier is connected to ITH, but abnormal confusion.
Is there any good way?
Two good fits for this application would be the LT3757A or the LTC3862. Check out LTpowerCAD for design help.

Formally you can not do this, because violation of SW pins ABS MAX. You might take a look at non-sync boost controller as LTC3862-1.
You can use LT3571 with APD Voltage: up to 70V. You might use LTC3862-1 for higher voltages to bias avalanche photodiodes, but I'm not aware of verified solutions at this time. For the rest of the questions please contact local ADI support center…
