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

Demonstration circuit 1168 is a current mode synchronous switching regulator featuring the LTC3810-5. The circuit is configured as a synchronous step-down regulator operating at 250kHz switching frequency. Output voltage is 12V at 10A maximum load. The input voltage range is 14V to 60V.

The LT1965 series are low noise, low dropout linear regulators. The devices supply 1.1A of output current with a 310mV typical dropout voltage. Operating quiescent current is 500?A for the adjustable version, reducing to <1?A in shutdown. Quiescent current is well controlled; it does not rise in dropout as with many other regulators. The LT1965 regulators have very low output noise which makes them ideal for sensitive RF and DSP supply applications.Output voltage ranges from 1.20V to 19.5V. The LT1965 regulators are stable with output capacitors as low as 10?F. Internal protection circuitry includes reverse-battery protection, current limiting with foldback, thermal limiting and reverse-current protection. The LT1965 series are available in fixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V, and as an adjustable device with a 1.20V reference voltage. The package offerings include the 5-lead TO-220, 5-lead DD-Pak as well as the thermally enhanced 8-lead MSOP and low profile (0.75mm) 8-lead 3mm ? 3mm DFN.Applications Logic Power Supplies Post Regulator for Switching Supplies Low Noise Instrumentation

Demonstration circuit DC1180 is a dual output regulator consisting of two identical constant frequency step-down converters, based on the LTC3407A monolithic dual synchronous buck regulator in the 3 × 3 DFN-10 package. The LTC3407A is similar to the LTC3407 but has a lower ripple Burst Mode operation and includes an optional external soft-start. The DC1180 has an input voltage range of 2.5V to 5.5V, and either output is capable of delivering up to 600mA of output current. In Burst Mode® operation, the DC supply current is typically only 25 µA (per channel) at no load, and less than 1 µA in shutdown. The DC1180 is a very efficient circuit: up to 96% for either circuit.
