Hi,
We do Full bridge 220vin 250khz, 500wout, 28vout
Do you agree, for current mode control, the CST output ramp should be connected to both the RAMP pin and the ILIM pin.?
We have been given a circuit and the current sense voltage gets divided down, then fed to the ILIM pin, ..when the CS voltage has already been fed to the RAMP pin.
It doesnt seem to make sense, though im just wondering if im havign a brain trip-out?
