Demonstration circuit EVAL-LT8692S-AZ is an ultracompact 4 rail power supply featuring the LT8692S, a 42V quad monolithic synchronous step-down Silent Switcher®. The demo circuit is designed for 5V, 3.3V, 1.8V, and 1.2V outputs from a nominal 12V input. The 3.3V, 1.8V and 1.2V converters are powered from the high voltage buck regulator with 5V output, which is powered from a wide range of 6.2V to 42V input. The current capability is 2A for the channel 1, and 1A for the low voltage channels. Internal soft-start, individual current limit, independent enable for each channel simplify the complex design of quad-output power converters. All regulators can be synchronized to a common external clock input or internal oscillator of 2MHz. The table in the demo manual summarizes the performance of the demo board at room temperature. The circuit can be easily modified for different applications. The LT8692S data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with the quick start guide for demo circuit EVAL-LT8692S-AZ.

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.

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.
