The LTC2328-18 is a low noise, high speed 18-bit successive approximation register (SAR) ADC with pseudo-differential inputs. Operating from a single 5V supply, the LTC2328-18 has a ?10.24V true bipolar input range, making it ideal for high voltage applications which require a wide dynamic range. The LTC2328-18 achieves ?5LSB INL maximum, no missing codes at 18 bits with 95dB SNR.The LTC2328-18 has an onboard single-shot capable reference buffer and low drift (20ppm/?C max) 2.048V temperature compensated reference. The LTC2328-18 also has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisy-chain mode. The fast 1Msps throughput with no cycle latency makes the LTC2328-18 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2328-18 dissipates only 50mW and automatically naps between conversions, leading to reduced power dissipation that scales with the sampling rate. A sleep mode is also provided to reduce the power consumption of the LTC2328-18 to 300?W for further power savings during inactive periods.

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 2560A is a 18V, 10A synchronous step-down Silent Switcher®2 with spread spectrum frequency modulation featuring the LT8642S. The demo board is designed for 1.2V output from a 2.8V to 18V input. The LT8642S is a compact, ultralow emission, high efficiency, and high speed synchronous monolithic step-down switching regulator. The integrated bypass capacitors optimize all the fast current loops and make it easier to minimize EMI/EMC emissions by reducing layout sensitivity. Selectable spread spectrum mode can further improve EMI/EMC performance. Fast minimum on-time of 20ns enables high VIN to low VOUT conversion at high frequency. The LT8642S switching frequency can be programmed either via a resistor or external clock over a 200kHz to 3MHz range. The default frequency of demo circuit 2560A is 2MHz. The SYNC pin on the demo board is grounded (JP1 at BURST position) by default for low ripple Burst Mode® operation. To synchronize to an external clock, move JP1 to SYNC and apply the external clock to the SYNC terminal. Spread spectrum mode and forced continuous mode can be selected respectively by moving JP1 shunt. The demo board has an EMI filter installed. This EMI filter can be included by applying the input voltage at the VIN_ EMI terminal. The LT8642S data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this demo manual for demo circuit 2560A. The LT8643S is assembled in a 4mm × 4mm LQFN package with exposed pads for low thermal resistance. The layout recommendations for low EMI operation and maximum thermal performance are available in the data sheet section Low EMI PCB Layout and Thermal Considerations.

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.

The LTC4246 contains eight switches, each with an independent circuit breaker function. It is particularly well suited for extremely space constrained designs. Each switch can operate completely autonomously or be arbitrarily grouped with other switches that will respond together to the fault of any single device within its group. Optionally, channel grouping may be extended to multiple LTC4246 devices by selecting the FIN# (fault input) pin as part of a channel group. A required bias supply between 2.5V to 5V allows the switches to independently operate from 13.2V down to 0V. The LTC4246 provides an SPI serial interface to enable, disable and configure the timing and current thresholds of each channel as well as provide status to each channel?s fault state.A common open-drain FAULT status output indicates if any switch has opened due to a circuit breaker event.APPLICATIONSATE Wafer Probe ElectronicsScope Probe ProtectionIndustrial ControlRelay Replacement

The LTC3426 step-up switching regulator generates an output voltage of up to 5.5V from an input voltage as low as 1.6V. Ideal for applications where space is limited, it switches at 1.2MHz, allowing the use of tiny, low cost and low profile external components. Its internal 2A, 100m? NMOS switch provides high efficiency even at heavy load, while the constant frequency, current mode architecture results in low, predictable output noise that is easy to filter.Anti-ringing circuitry reduces EMI concerns by damping the inductor while in discontinuous mode, and internal soft-start eases inrush current worries. Internal frequency compensation is designed to accommodate ceramic output capacitors, further reducing noise. The device features very low shutdown current of 0.5?A.The LTC3426 is available in the 6-lead SOT-23 package.Protected by U.S. Patents, including 6498466, 6611131Applications White LED Driver Supply Local 3.3V or 5V Supply Battery Back-Up
