General Description
The FP103 is a single chip composed of one independent OP-AMP (OPA2) and another OP-AMP (OPA1) with a 2.5V precision voltage reference on non-inverting input. It offers space and low cost in many applications such as the secondary feedback control of power supply, DC/DC converter or adaptor.
The FP103 is designed for regulator feedback circuit with few external components. The circuit diagram for typical application is shown as below.
