The LT3825 is an isolated switching regulator controller designed for medium power flyback topologies. A typical application is 10W to 60W with input voltage limited only by external power path components. A third transformer winding provides output voltage feedback.The LT3825 is a current mode controller that regulates output voltage based on sensing secondary voltage via a transformer winding during flyback. This allows for tight output regulation without the use of an opto-isolator, improving dynamic response and reliability. Synchronous rectification increases converter efficiency and improves output cross regulation in multiple output converters.The LT3825 operates in forced continuous conduction mode which improves cross regulation in multiple winding applications. Switching frequency is user programmable and can be externally synchronized. The part also has load compensation, undervoltage lockout and soft-start circuity.Applications Isolated Medium Power (10W to 60W) Supplies Isolated Telecom, Medical Converters Instrumentation Power Supplies Isolated Power over Ethernet Supplies

This design is a digitally controlled: two phase interleaved: 700W power factor correction converter with added power metering functionality. A C2000™ Piccolo™ microcontroller is the controller for the two 180 ° phase shifted boost power stages that comprise the power factor correction converter: and: additionally: it monitors the line and neutral voltage waveforms to implement power metering functions. This design is able to achieve 97% efficiency and 1.5% THD at full load with power factor greater than 0.98. By minimizing power loss in the power stage: reducing reliability impacts of harmonic distortion: and providing near unity power factor: this design is a great choice for off-line applications and AC/DC power supplies.

Today's digital signal processor (DSP) architectures are confronted with the tough requirement of addressing a wide-range of standards and meeting a cost-effective performance/power trade-off. Increasing raw million instructions per second (MIPS) performance just by running at a higher frequency is not possible anymore since leakage is becoming a dominant factor with shrinking silicon geometries.
