Commodity IC Data: SG3525A
Q: I am having trouble doing detailed design of analog circuits for low-cost products using commonly-available ICs. In particular, the SG3525A PWM controller, popular for push-pull converter designs, lacks some useful design data, such as the transfer function of the error amplifier. Can you provide some of this information?
A: Some SG3525A PWM IC missing data is not really missing but can be hard to find.
