Hi,
I'm looking for a current mode controller (such as UC3842 or MC34063) in which I can have acess to the inverting input of the amplifier used for current measurement. The idea is to change the current by varying the reference voltage at which the comparator triggers, rather than having to use a potentiometer to vary the signal from the shunt resistor. Anyone aware of such a device?
Regards.
