The LTC3129 is a high efficiency, 200mA buck-boost DC/DC converter with a wide VIN and VOUT range. It includes an accurate RUN pin threshold to allow predictable regulator turn-on and a maximum power point control (MPPC) capability that ensures maximum power extraction from non-ideal power sources such as photovoltaic panels.The LTC3129 employs an ultralow noise, 1.2MHz PWM switching architecture that minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Built-in loop compensation and soft-start simplify the design. For high efficiency operation at light loads, automatic Burst Mode operation can be selected, reducing the quiescent current to just 1.3?A.Additional features include a power good output, less than 10nA of shutdown current and thermal shutdown.The LTC3129 is available in thermally enhanced 3mm ? 3mm QFN and 16-lead MSOP packages. For fixed output voltage options, see the functionally equivalent LTC3129-1, which eliminates the need for an external feedback divider.

DC183A: Demo Board for the LTC1598 8-Channel, Micropower Sampling 12-Bit Serial I/O A/D Converter.

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 AD5593R has eight input/output (I/O) pins, which can beindependently configured as digital-to-analog converter (DAC)outputs, analog-to-digital converter (ADC) inputs, digital outputs,or digital inputs. When an I/O pin is configured as an analogoutput, it is driven by a 12-bit DAC. The output range of theDAC is 0 V to VREF or 0 V to 2 ? VREF. When an I/O pin isconfigured as an analog input, it is connected to a 12-bit ADCvia an analog multiplexer. The input range of the ADC is 0 V toVREF or 0 V to 2 ? VREF. The I/O pins can also be configured tobe general-purpose, digital input or output (GPIO) pins. Thestate of the GPIO pins can be set or read back by accessing theGPIO write data register and GPIO read configuration registers,respectively, via an I2C write or read operation.The AD5593R has an integrated 2.5 V, 20 ppm/?C reference thatis turned off by default and an integrated temperature indicatorthat gives an indication of the die temperature. The temperaturevalue is read back as part of an ADC read sequence.The AD5593R is available in 16-lead TSSOP and LFCSP, as wellas a 16-ball WLCSP, and operates over a temperature range of?40?C to +105?C.Applications Control and monitoring General-purpose analog and digital I/O

Demonstration circuit 1590B is a dual output synchronous buck converter featuring the LTC3880EUJ, a dual output peak current mode controller with digital power system management. There are two versions of the board available: DC1590B-A senses the output current across a sense resistor and has a default switching frequency of 350kHz, and DC1590B-B senses output current with the inductor DCR and has a default switching frequency of 425kHz. Either version can be populated with the LTC3880EUJ-1 (which allows the user to provide bias power to the IC from an external power supply) instead of the LTC3880EUJ. These boards provide two programmable outputs of 20A each. The factory default settings are 1.8V for each output.

Demonstration circuit 2314A is intended to demonstrate the performance of the LTC4236-1/LTC4236-2 Dual Ideal Diode-OR and Single Hot Swap Controller with Current Monitor. The controller operates in redundant supply circuits, where each rail has an individual ideal diode, and the outputs are connected to the load through a single Hot Swap circuit. The controller enables monitoring of the load current by providing a signal that is 100× the sense resistor voltage.
