Demonstration circuit 1247A features the LT3582 an I2C Programmable Boost and Single Inductor Inverting DC/DC Converters with OTP. It converts a 2.7V-5.5V source to two outputs, a positive and a negative. The positive output can be programmed from 3.2V to 12.775V at 25mV intervals and the negative from -1.2V to -13.95V at 50mV intervals, all via the QuickEval™ System. A DC590B is needed for evaluation of this demo board. Table 1 below shows the maximum expected load currents for some output/input combinations. Check Maximum Load Current section on datasheet for other combinations. The LT3582 features all integrated switches and feedback resistors, a low noise control scheme, positive output disconnect function, low quiescent current, built in softstart.

Demonstration circuit 2668A is optimized for evaluation of the LTC5552 passive double-balanced mixer. Its RF port is broadband matched from 3GHz to 20GHz, and the internal LO amplifier, requiring only a 0dBm drive level, is broadband matched to 50Ω from 1GHz to 20GHz with 10dB Return Loss. The differential IF output is usable from DC to 6GHz. The LTC5552 can be used for upconverting and downconverting applications.

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.

Demonstration circuit 2810A features the LTM4673: the wide input and output voltage range, high efficiency and power density, quad output DC/DC step-down μModule® regulator with Digital Interface for control and monitoring. The DC2810A default input voltage range is 4.5V to 15V. However, if VIN is lower than 4.5V, minor modification to certain existing onboard components is required. Please refer to Step 8: Operation at VIN ≤ 4.5V in Quick Start Procedure section. The factory default output voltages are VOUT0 = 1V, VOUT3 = 0.9V at 12A per channel; VOUT1 = 1.2V, VOUT2 = 1.8V at 5A per channel. The DC2810A output voltages can be adjusted from 0.6V up to 3.3V for channel 0 and channel 3 and from 0.6V to 5.5V for channel 1 and channel 2. The default switching frequencies are 600kHz for channel 0 and channel 3 and 1MHz for channel 1 and channel 2. Forced airflow and heatsink might also be used to further optimize the output power when all output rails are on and fully loaded. Programming the output voltages to values greater than 1.8V, may require derating output current based on thermal derating curves provided in the data sheet of the LTM4673. The DC2810A comes with PMBus interface and digital power system management functions. An onboard 12-pin connector is available for users to connect the dongle DC1613A to the DC2810A and provides an easy way to communicate and program the part using LTpowerPlay® software development tool. LTpowerPlay software and I2C/PMBus/SMBus Dongle DC1613A allows users to monitor real time telemetry of input and output voltages, input and output current, internal IC die temperatures, and fault logs. The LTM4673 is available in a thermally enhanced, low profile, 361-Lead (16mm × 16mm × 4.72mm) BGA package. It is recommended to read the data sheet and demo manual of LTM4673 prior to use or making any hardware changes to DC2810A. LTpowerPlay software can be downloaded here. The USB to PMBus Controller Dongle DC1613A for use with LTpowerPlay is available here.

The DC2872A is an evaluation board for demonstrating the performance and ease of use of the LTM2985, an isolated 10-channel temperature measurement system on a chip, software compatible with the LTC2986-1. It provides 5kV isolated power and SPI interface to the precision temperature-to-bits converter.

Demonstration Circuit 3001A-B showcases the LTC4451 ideal diode controller with an integrated low RDS(ON) MOSFET. The board includes two independent LTC4451 ideal diodes sharing a common ground and operates over a range of 0V to 40V, carrying up to 8A at 25°C ambient temperature. The board can be set up in a diode-OR configuration by connecting the output channels together. NOTE: Although the DC3001A-B can carry 8A at 25°C, the LTC4451 is designed for a max current of 7A across –40°C to 125°C. Please follow the data sheet recommendations to design your application across the operating temperature range.
