Demonstration circuit 825 is a monolithic step-down DC/DC switching regulator featuring the LT1936. The demo board is optimized for 3.3V output at 1.2A from a 4.5V to 36V input or a 5V, 1.2A output from a 6.8V to 36V input. The output is selectable by placing the JP1 jumper at the 3.3V or 5V position.

The LTC2444/LTC2445/LTC2448/LTC2449 are 8-/16- channel (4-/8-differential) high speed 24-bit No Latency ?? ADCs. They use a proprietary delta-sigma architecture enabling variable speed/resolution. Through a simple 4-wire serial interface, ten speed/resolution combinations 6.9Hz/280nVRMS to 3.5kHz/25?VRMS (4kHz with external oscillator) can be selected with no latency between conversion results or shift in DC accuracy (offset, full-scale, linearity, drift). Additionally, a 2X speed mode can be selected enabling output rates up to 7kHz (8kHz if an external oscillator is used) with one cycle latency.Any combination of single-ended or differential inputs can be selected with a common mode input range from ground to VCC, independent of VREF. While operating in the 1X speed mode the first conversion following a new speed, resolution, or channel selection is valid. Since there is no settling time between conversions, all 8 differential channels can be scanned at a rate of 500Hz. At the conclusion of each conversion, the converter is internally reset eliminating any memory effects between successive conversions and assuring stability of the high order delta-sigma modulator.Applications High Speed Multiplexing Weight Scales Auto Ranging 6-Digit DVMs Direct Temperature Measurement High Speed Data Acquisition

The LTC3499/LTC3499B are synchronous, fixed frequency step-up DC/DC power converters with integrated reverse battery protection that protect and disconnect the devices and load when the battery polarity is reversed while delivering high efficiency in a small (3mm ? 3mm) DFN package. True output disconnect eliminates inrush current and allows zero load current in shutdown.The devices feature an input voltage range of 1.8V to 5.5V enabling operation from two alkaline or NiMH batteries. The switching frequency is internally set at 1.2MHz allowing the use of tiny surface mount inductors and capacitors. A minimal number of external components are required to generate output voltages ranging from 2V to 6V. The LTC3499 features automatic Burst Mode operation to increase efficiency at light loads, while the LTC3499B features continuous switching at light loads.The soft-start time is externally programmable through a small capacitor. Anti-ring circuitry reduces EMI emissions by damping the inductor in discontinuous mode. The devices feature <1?A shutdown supply current, integrated overvoltage protection and are available in both 8-pin (3mm ? 3mm) DFN and 8-pin MSOP packages.Applications Medical Equipment Digital Cameras MP3 Players Handheld Instruments
