DC748A: Demo Board for the High Accuracy 3GHz Log RF Detector Has 60dB Dynamic Range.

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 2616A-D features a polyphase design using the LTM4647EY, a 30A high efficiency, switch mode step-down power µModule regulator. The input voltage range is from 6V to 15V. To use DC2616A-D for input voltage range from 4.7V to 6V, connect INTVCC to SVIN (change R22, R42, R55, R68 from OPT to 0Ω), DRVCC to VIN (change R21, R38, R52, R65 from 0Ω to OPT, R2, R39, R53, R66 from OPT to 0Ω). The output voltage range is 0.6V to 1.8V. The DC2616A-D can deliver a nominal 120A output current with four LTM4647 modules in parallel. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT, and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper selects pulseskipping mode for noise sensitive applications or burst mode operation in less noise sensitive applications. The MODE_PLLIN pin also allows the LTM4647 to synchronize to an external clock signal. The phase shift between two adjacent phases is 90 degrees. DC2616A-D has the option of choosing both internal and external compensation circuit for LTM4647. The LTM4647 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2616A-D.

The LT3966 is an I2C programmable monolithic boost LED driver with four independent channels. Each channel provides a 60V current mode boost converter with an internal 1.6A DMOS power switch, as well as internal and external analog and PWM dimming features. I2C programmable features include a 13-bit (8192:1) digital PWM generator, 8-bit analog dimming DAC, and flexible fault reporting and handling.An onboard 8-bit ADC allows measurement of each channel?s output voltage and output current, as well as chip input voltage and two external measurements. In addition, independent shutdown and standby control of each channel provides flexible solutions for multitopology applications.The LT3966 is available in a thermally enhanced 6mm ? 6mm 40-Lead QFN package.ApplicationsBacklightingHeads Up Displays

Demonstration circuit 2807A features the LTC6560 single channel transimpedance amplifier (TIA) with output multiplexing. The DC2807A accepts voltage pulses and converts them to current for the TIA. The LTC6560, which features 74kΩ transimpedance gain and 30µA linear input current range, is ideal for LIDAR receivers using avalanche photodiodes (APD). The LTC6560 operates from 5V single supply and consumes only 90mW. Utilizing the LTC6560’s output MUX, multiple LTC6560 devices can combine into a single output. The LTC6560’s fast overload recovery makes it well suited for LIDAR receivers. The LTC6560’s single-ended output can swing 2VP-P into a 100Ω load. The LTC6560 is packaged in a compact 3mm × 3mm 16-pin leadless QFN package with an exposed pad for thermal management and low inductance.
