Hi Brian,
Yes, when you tie the ISN to ground, the circuit will see a shorted output. You must connect your load from ISN to GND to operate. I have tried placing a load (212 Ohm) from ISN to GND and the Gate started switching. You can try simulating with…
Hi,
I'm looking for LED driver, need buck-boost and constant current-CC.
Vin=24V
Vout=12-48V, constant mode 3-4A, and 10A in pulse mode (for a short time) how to achieve this? using PWM?
I'm currently looking at LT3796, is it capable to achieve…
We are designing a battery charger using LT3796 and now we are in need to know how to set the o/p current.
We have two cases,
1.Vctrl is more than 1.2V, by the time the we have a sense resistor of 0.16Ohm so according to calculation 250mv/0.1Ohm=2.…
Hi!
It was with great interest I read Xin Qi's article in the July 2012 issue of Analog Innovation. We have been prototyping a MPT charger, based on the LT3652. It works well on the bench and in field trials, but has its limitations. First the max current…
Hi
Among regulators LT3796, LTC3779 & LT3756 which is the best regulator to implement a Constant current source with an output voltage of 96V. Suggest if any better regulators are available.
Regards & Thanks

I am investigating using an LTC6908 in an application with multiple power converters. In this application, it would run at a nominal frequency of 560 kHz (504 kHz to 616 kHz with spreading). I am hoping to confirm that all the converters that will be…
I need to implement a buck battery charger for a 10s4p Li-ion pack, Vin 48VDC. with the additional requirement that Iout should be selectable from a MCU (i.e. conmuting between different programming resistors).
LTC4013 looks great, but one thing worries…
I am designing a battery charger for an existing battery pack design of 28 11000mAh NiMH cells. The goal is to design a charger with a constant current output of 3.0A with low DC ripple. The LT3795 and LT3796 Drivers seem to be a good fit for my application…
Hi FormerMember
In LTC3779 data-sheet it is mentioned, " Constant-Current Regulation (IAVGSNSP and IAVGSNSN Pins)The LTC3779 provides a constant-current regulation loop for either input or output current. A sensing resistor close to the input or
