I am looking for the pspice model of the controller LTC3703 I am currently working with.
Do you know where to find it ?
I have a problem with the current limit function of the device.
I disabled the function but the IC still limit the current while the voltage at the RUN/SS-Pin is reduced.
I only have a load current of 0,5A@24V output voltage.
I didn't understand…
I am trying to use the LTC3703 in boost mode to create 24V from 12V SLA batteries. I have copied the example circuit on page 34 of the LTC3703 datasheet and am using the suggested inductor and mosfets. The circuit draws a lot of current (around 800mA…
I designed step-down synchronous converter based on typical application of LTC3703 (it's a student project). I experience some repeatable misbehavior in switching waveforms :<
My converter runs from 4,5 [V] to 30 [V] supply @ 455 [kHz], pulse skip…
Thanks a lot .
I see. LTC3703 ErrAmp is voltage amp.
ILTC4000 will be interfaced to control through the FB pin(LTC3703).
I have more question about
" The ITH output of the LTC4000 should be connected through an inverting buffer, and a resistor…
In LTC4000 + LTC3703 start up and reset condition
I think below sequence is good.
Power supply:LTC4000 > LTC3703
EN:LTC3703 RUN_EN > LTC4000 ENC_EN
Because Battery have supply path in LTC4000 disable.(Bgate's Pch is on.)
Are these consideration…
您可以看一下LTC的，高壓輸入可達100V，若做Buck 輸出要24V 15A 的話，可以看一下LTC3703。
5V to 60V is a very wide VIN range. What is the source? Is the plan to run the LTC3703 as a boost and a buck?
What is ment by "* In regard to the system, regardless of step-up / step-down / step-up / step-down" ?
The 4000 can be…
