General Description

The FP702 is composed one op-amp (OPA) with a 1.25V precision voltage reference on inverting

input with an open collector output. It is applied to offer space and low cost in many applications such

as the secondary feedback control of power supply, AC / DC converter or adaptor.

The FP702 is designed as an OVP detector with few external components. The circuit diagram of

typical application example is shown as below:
