DC918C-J: Demo Board for the LTC2206-14 14-Bit, 80Msps ADC.

DC928A: Demo Board for the LTC3452 Synchronous Buck-Boost MAIN/CAMERA White LED Driver.

The LTC2484 combines a 24-bit No Latency ??? analog-to-digital converter with patented Easy Drive? technology. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances and input signals with rail-to-rail input range to be directly digitized while maintaining exceptional DC accuracy.The LTC2484 includes an on-chip oscillator. The LTC2484 can be configured to reject line frequencies. 50Hz, 60Hz or simultaneous 50Hz/60Hz line frequency rejection can be selected as well as a 2? speed-up mode.The LTC2484 allows a wide common mode input range (0V to VCC) independent of the reference voltage. The reference can be as low as 100mV or can be tied directly to VCC. The LTC2484 includes an on-chip trimmed oscillator, eliminating the need for external crystals or oscillators. Absolute accuracy and low drift are automatically maintained through continuous, transparent, offset and full-scale calibration.Applications Direct Sensor Digitizer Weight Scales Direct Temperature Measurement Strain Gauge Transducers Instrumentation Industrial Process Control DVMs and Meters

DC947A: Demo Board for the LT3740 Wide Operating Range, Valley Mode, No RSENSE Synchronous Step-Down Controller.

The LT3478/LT3478-1 are 4.5A step-up DC/DC converters designed to drive LEDs with a constant current over a wide programmable range. Series connection of the LEDs provides identical LED currents for uniform brightness without the need for ballast resistors and expensive factory calibration.The LT3478-1 reduces external component count and cost by integrating the LED current sense resistor. The LT3478 uses an external sense resistor to extend the maximum programmable LED current beyond 1A and also to achieve greater accuracy when programming low LED currents. Operating frequency can be set with an external resistor from 200kHz up to 2.25MHz. Unique circuitry allows a PWM dimming range up to 3000:1 while maintaining constant LED color. The LT3478/LT3478-1 are ideal for high power LED driver applications such as automotive TFT LCD backlights, courtesy lighting and heads-up displays. One of two CTRL pins can be used to program maximum LED current. The other CTRL pin can be used to program a reduction in maximum LED current vs temperature to maximize LED usage and improve reliability.Additional features include inrush current protection, programmable open LED protection and programmable soft-start. Each part is available in a 16-pin thermally enhanced TSSOP Package.Applications High Power LED Driver Automotive Lighting

Demonstration circuit 952 is a current mode synchronous switching regulator featuring the LTC3810. The circuit is configured as a synchronous step-down regulator operating at 230kHz switching frequency. Output voltage is 12V at 6A maximum load. The input voltage range is 13V to 80V.

Demonstration circuit 960 is a high voltage, current-mode DC/DC step-down controller featuring the LTC3824 in a small 10-pin MSOP package. The board operates from an input voltage of 5.5V to 60V and outputs 5V @ 2A. The converter uses a P-channel MOSFET for the main switch resulting in a low parts count design. Operating frequency is set to 200kHz with the option to accept a synchronized external clock.

Demonstration circuit 965A is a single output high frequency step-down DC/DC converter featuring the low quiescent current LTC3835-1 in a 16-pin narrow SSOP package. The DC965A is programmed to generate a regulated 3.3V@5A output from a 4.5V to 36V input voltage. The LTC3835-1 is similar to the LTC3835 but has reduced functionality (it does not have PGOOD, ExtVCC or CLOCKOUT pins).
