Demonstration circuits 1053A-E through 1053A-H exercise the LTC3526L family of high efficiency synchronous boost converters, and are capable of operating with an input voltage range from 0.8V to 5.5V. The 2 × 2 mm DFN thermally enhanced package, high switching frequency (1MHz or 2MHz) and 550mA internal power switches provide a very tiny solution. The LTC3526L family also features output disconnect, and the input voltage can be greater or less than the output voltage. DC1053A-G features the LTC3526L-2 (Burst mode operation) and the DC1053A-H features the LTC3526LB-2 (Burst mode defeated). Both have a 2MHz switching frequency and use a 2.2µH inductor.

Demonstration circuit 1060 features two LT3508 step-down DC/DC switching converters. One circuit uses the LT3508EFE and the other circuit has the LT3508EUF. The LT3508 dual output step-down switching regulator has two internal power switches, a wide input voltage range, adjustable switching frequency synchronizable over the frequency range, programmable soft-start, tracking, power-good, and channel sequencing. The anti-phase switching reduces the input capacitor. The wide VIN range of the LT3508 allows step-down configurations with up to 36V input. The high power internal switches have current limit that allows for up to 1.4A output on each output. The demonstration circuit has two circuits. The top is optimized for high efficiency, wide input range and maximum output current; the bottom is optimized for the size. The top circuit is rated for 3.3V at 1.4A and 5V at 1.4A output from a 6V–36V input using the FE package. The frequency is set to 700kHz to allow for the high VIN to VOUT ratio and provides high efficiency throughout the range. The bottom circuit generates 1.8V at 1A and 3.3V at 1A from a 5V to 16V DC input using the QFN package and shows off the compact size with 1.6MHz switching frequency.

The LTC2751 is a family of 12-, 14-, and 16-bit multiplying parallel-input, current-output DACs. They operate from a single 2.7V to 5.5V supply. All parts are guaranteed monotonic over temperature. The LTC2751A-16 provides 16-bit performance (?1LSB INL and DNL) overtemperature without any adjustments. These SoftSpan? DACs offer six output ranges ? two unipolar and four bipolar ? that can be programmed through the parallel interface, or pin strapped for operation in a single range.These parts use a bidirectional input/output parallel interface that allows read back of any on-chip register. A power-on circuit resets the DAC output to 0V when power is initially applied. A logic low on the CLR pin asynchronously clears the DAC to 0V in any output range. The parts are specified over commercial and industrial temperature ranges.Applications High Resolution Offset and Gain Adjustment Process Control and Industrial Automation Automatic Test Equipment Data Acquisition Systems
