The compensation inside LTC3892 block diagram looks like voltage ( pin Vfb) and current (pin sense+-) compensation in series. Can I use voltage compensation only? How do I disable (or modify) the current compensator?
I think the ltc3892 uses a depletion FET between the TG and SW pins. That would make it appear shorted when the device is off. I have been using this chip for a while and have seen that, but when operating the gate drive is fine.
I am finding that the LTC3892 appears to be having the high side gate drivers getting killed. I looked through the datasheet and it does not indicate the drive current that the high side gate drive can source.
I am using the LTC3892 for dual 9A 36V outputs. I have noticed that using one channel/side of the LTC3892 everything works but as soon as I turn on the other side the voltages start turning on and off and the the LT3892 gets hot.
