I refer to two (2) devices used for control of LLC DC-DC converter: L6599, and the newer L6699.In our application, we must enable and disable the gate drive output pulses via a separate signal. The transition from ENABLE to DISABLE must be instantan...

There are three variants of the L6599 product, but we are using the L6599AT so we will focus on just two of these variants: the L6599A, and the L6599AT. Here is the problem: The datasheet for the L6599A seems to be quite comprehensive and complete, w...

We noticed that there are pulses at the gate drive outputs (pins 15 HVG, & 11 LVG) during the ramp-up of the control voltage (pin 12 VCC).This is what we saw: when VCC reaches about 11V, a sequence of pulses appear on both LVG and HVG. First LVG went...

Question 1:In our circuit Pin 5 STBY is pulled down to 0V to instantly stop pulses on gate drives. But sometimes when STBY=0V we still see pulses at the gate driver outputs LVG, HVG. The datasheet does not mention that gate pulses may still happen.I ...

Hello Sir/Madam,Product PN: STWD100xY.Problem: The problem is not with the actual product itself, but with the datasheet. The existing datasheet makes it very difficult to determine if the product is suitable for our application. For the value for ...
