Power integrations flybacks

1 post / 0 new


Are there any two power integrations flyback chips from different ranges which essentially are the same as each other? There are a lot of different chips and i wonder if there is overlap here (not complaining, but just getting used to the range so we can select). Also, why do the block diagrams not showthe ramp generator for the voltage mode ones? Also, do any PI chips have an internal error amplifier?
