Demonstration circuit 1320 is a high power density step-down DC/DC converter featuring the LTC3608EWKG (DC1320A-A) or the LTC3609EWKG (DC1320A-B) high current, high input voltage monolithic DC/DC step-down converter. The input voltage of the DC1320A-A is from 5V to 20V and it provides a jumper-selectable output voltage of 1.5V, 1.8V, 2.5V, or 3.3V @ 8A.

Demonstration circuit 3006A is a compact no-opto isolated flyback converter featuring the LT3001. The DC3006A outputs 12V, and maintains tight regulation with as load current from 1.5mA up to 300mA over an input voltage from 4V to 32V. The output current capability increases with the input voltage, as shown in the Performance Summary table. Transformer leakage inductance causes a voltage spike on the primary side after the power switch turns off. The leakage inductance spike is limited within the MOSFET’s voltage rating of 65V with an RC snubber and a TVS clamp which damp the ringing and clamp the MOSFET drain voltage to a safe level.  The Performance Summary table summarizes the performance of the demo board at room temperature. The demo circuit can be easily modified for different applications with some pre-designed transformers. The LT3001 datasheet gives a complete description of the part, operation and application information. The datasheet must be read in conjunction with this quick start guide for demo circuit 3006A.

Demonstration circuit DC330 comprises two low noise micropower voltage regulators using the LT1761 in the 5-lead SOT-23 package. These circuits are primarily used in cellular phones, voltage controlled oscillators, RF power supplies and as local regulators in larger systems. Their ability to tolerate a wide variety of output capacitors makes them ideal in space- and cost-sensitive systems.

Demonstration circuit DC339-A is a low noise micropower voltage regulator using the 150mA output current LT1762 linear regulator in an 8-lead MSOP package. The demo board has an input voltage range from 2.3V to 20V and a jumper-selectable output votlage that can be set to 1.22V, 2.5V, 3.0V, 3.3V, 5V or a user-defined value. The LT1762's low 20µVRMS (10Hz to 100kHz bandwidth) output noise and low 30µA quiescent current make the device ideal for voltage-controlled oscillators, RF power supplies and local regulators in larger systems.
