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.

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.

DC962A-A: Demo Board for LT6600-2.5 Very Low Noise, Differential Amplifier and 2.5MHz Lowpass Filter.

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).

Demonstration circuit 986 is a Triple Step-Down LED Driver featuring the LT3496EUFD. The LT3496 is a triple output DC/DC converter designed to operate as current sources for driving high current LEDs. Each ofthe three regulators on the demo board is independently operated. The default current for each output channel is 500mA. The output current should not exceed the rated current of the LEDs used.  The maximum voltage of an LED string the demo board can drive is limited by the duty cycle and the input voltage of the LT3496. The maximum power input voltage (PVIN ) is 45V. As a result, each channel of the demo board can drive up to ~31V total LED voltage. The LT3496's input voltage range is 3V to 30V (with 40V transients), however to minimize power dissipation the demo board uses a 3V to 5.5V supply.
