Demonstration circuit 877 is a high efficiency synchronous Buck-Boost converter using the LTC3531-3.3. The input range is from 1.8V to 5.5V making it ideal for single-cell  Lithium-Ion, multicell alkaline or nickel battery applications. This converter can provide 200mA when the input voltage is above 2.9V. The DC877 features the LTC3531-3.3 in a tiny 6-pin ThinSOT package. The converter operates in Burst Mode, which provides conversion efficiency over a wide range of load currents. It has minimum component count and tiny solution size. Other features include current limiting, thermal shutdown and output disconnect.

Demonstration circuit 879 is a Micropower Synchronous Step-Up Converter with Output Disconnect featuring the LTC3525-3.3 and LTC3525-5. The LTC3525 is a high performance Burst Mode operation only, synchronous boost converter. The LTC3525 incorporates a feature that maximizes efficiency by adjusting the peak and valley of the inductor current as a function of load. The demo board has two assembly versions: DC879A-A and DC879A-B. The DC879A-A offers fixed 3.3V output. The DC879A-B offers fixed 5V output. They offer a compact, high efficiency solution in single cell or dual cell alkaline or Li-ion applications. Only three small external components are required.

Demonstration circuit 950A-A is an isolated, 30W multi-output, synchronous flyback converter in 1/8 brick format featuring the LT3825. Output voltage sensing is implemented without the use of opto-coupler, by sensing the voltage across a primary side auxiliary winding. A load compensation circuit is used to compensate for voltage drops caused by load currents. DC950A-A has input voltage range 36V-72V and features the LT3825. Demonstration circuit 950A uses a transformer design with tapped secondary winding, to achieve higher efficiency and better cross regulation than is possible with a transformer that uses a separate winding for each output.

Demonstration circuit 950A-B is an isolated, 30W multi-output, synchronous flyback converter in 1/8 brick format featuring the LT3837. Output voltage sensing is implemented without the use of opto-coupler, by sensing the voltage across a primary side auxiliary winding. A load compensation circuit is used to compensate for voltage drops caused by load currents. DC950A-B has input voltage range 9V-36V. Demonstration circuit 950A uses a transformer design with tapped secondary winding, to achieve higher efficiency and better cross regulation than is possible with a transformer that uses a separate winding for each output.
