Demonstration circuit 1734A features the dual channel LT8582 in boost and inverting regulator configurations. The circuit is designed to convert a 5V to 10V input source to 12V at 900mA and –12V at 590mA. To limit the temperature rise of the chip to 40°C, on the demo board with no air flow, the maximum combined output power is 15W. Additional input bulk capacitance may be needed, subject to source impedance. DC1734A is designed to survive output short circuit events.

Demonstration circuit DC1198B-B features the LTM4607EV, a high efficiency, high density switch mode buck-boost power module. The LTM4607EV can regulate its output voltage from input voltage both above and below the output. The board accepts an input voltage from 6V to 36V and is set for an output voltage of 12V. The rated load current is 5A in boost mode and 12A in step-down operation. Derating is necessary for certain VIN, VOUT and thermal conditions. The switching frequency can be synchronized to external clock operating from 200kHz to 400kHz. This clock input can be used to reduce undesirable frequency harmonics and reduce input and output ripple when paralleling LTM4607 modules for even higher output current.

Demonstration circuit 2069A features LT8490, a high performance buck-boost converter that implements an MPPT function and flexible charging profiles suitable for most battery types such as flooded and sealed lead acid batteries and Lithium-Ion batteries, and can operate from input voltages above, below or equal to the battery voltage.

Demonstration circuit 2234A is a synchronous sepic converter featuring the LT8711 multitopology switching controller. The LT8711 is a current mode PWM DC/DC controller with a dual input LDO to optimize gate driver efficiency. Ultralow 15μA quiescent current in low noise Burst Mode® operation achieves high efficiency at very light loads and helps extend the run-time in battery powered applications when in standby mode. The LT8711 switching frequency can be programmed either via oscillator resistor or external clock over a 100kHz to 750kHz range.

Demonstration circuit 2310A is optimized for evaluation of the LTC5549 passive double-balanced mixer with integrated LO frequency doubler. Its RF port is matched to 50Ω from 2GHz to 13.6GHz with 9dB return loss, and the LO port is matched to 50Ω from 1GHz to 12GHz with 10dB return loss. The IF output is matched to 50Ω from 700MHz to 6GHz with 10dB return loss. The LTC5549 can be used for upconverting and downconverting applications.

Demonstration circuit 2910A is low VIN, high efficiency, and dual 2A output µModule DC/DC converter. The board operates by default at a fixed 2MHz and can be synchronized from 1MHz to 3MHz via the MODE/SYNC pin. With its high switching frequency and current mode architecture, a fast transient response to line and load changes is possible without sacrificing stability. The DC2910A can be used in forced continuous mode or pulse skip mode for low noise, or in burst mode operation for high efficiency at light loads. The demo board features the LTM4691, which is available in a low profile 3mm x 4mm x 1.2mm LGA package. Please see the LTM4691 datasheet for more detailed information. It is recommended to read the data sheet for the LTM4691 prior to making any changes to the DC2910A.
