I've an old board with XC6SLX9 FPGA that needs 1.2V and 3.3V voltages; I must update the old board changing only the power and I'd like to use the LT8650S.
Is LT8650S suggested to power FPGA like XILINX SPARTAN6?
LT8650S.pdfI realized a board with LT8650S. The schematic is here attached.
My idea is to have two different OUTPUTs VH and VL_I from the LT8650S. The max current for VH will be 1.5A and the max current for VL_I will be 0.5A
In this circuit, I can change…
LT8646S and LT8650S have Vc pins that allow for external compensation and for two parts or channels to accurately share current. LT8610AC relies on internal compensation and does not have a Vc pin. Vc and FB pins should be tied together during…
I have a similar issue with the LT8650S. Any details you can share on what the actual solution was?
Hello, the LT8650S input range is 3V to 42V. It should work well for the range of the lipo batteries you had in mind.
I am looking for guidance on calculating the minimum inductance required to prevent subharmonic oscillation on the LT8650. I found the mention of APP NOTE 19 (which is an amazing reference) and the details there. I was not able to locate the Sx Voltage…
Im trying to find silent switcher solution for providing opamp type split rails from a suitable externally provided single rail supply - probably around 40ish volts perhaps even from PoE.
I like the idea of LT8650S type devices but I need split rails of…
Is it possible dual channel using below condition?
Are there any problem?
VIn range 5.8 to 39V
Vout1 3.3V 2.5A
Vout2 5V 5A
In the datasheet
"Both channels are designed for output currents up to 6A,but thermal considerations practically…
On behalf of Anthony Armstrong: The LT8614 is a Single Output step-down converter which can deliver up to 4A of continuous output current. We currently have four 42V input capable dual output devices: the LT8653S with dual 2A per channel, the LT8650S with…
thanks for your answer.
My question is about the possibility to use an external clock that is already SSFM ("A synchronizing signal that incorporates spread spectrum").
I know already that is possible to use Spread Spectrum XOR…
