The FP702, a 1-chip composed one op-amp (OPA) with a 1.25V precision voltage reference on inverting input and an open collector output, applied to offer space and low cost in many applications such as the secondary feedback control of power supply, AC/DC converter or adaptor.
Using few external components, FP702, a high performance integrated IC, is designed for an OVP detector. The circuit diagram of the typical application example is as below.
