The LT3753 is a current mode PWM controller optimized for an active clamp forward converter topology, allowing up to 100V input operation.A programmable volt-second clamp allows primary switch duty cycles above 50% for high switch, transformer and rectifier utilization. Active clamp control reduces switch voltage stress and increases efficiency. A synchronous output is available for controlling secondary side synchronous rectification.The LT3753 is available in a 38-lead plastic TSSOP package with missing pins for high voltage spacings.Applications Industrial, Automotive and Military Systems 48V Telecommunication Isolated Power Supplies

The LTC2937 is a 6-channel power supply sequencer and voltage supervisor. Supplies are enabled or disabled with precise user controlled order and time spacing. To detect power supply output faults during sequencing and monitoring, the LTC2937 accurately monitors supply turn-on/-off delays and output voltage levels. In the event of a fault, response actions include complete power supply shutdown and optional restarts. Root cause of power faults are logged to EEPROM. For systems with high supply count, a simple single wire connection between multiple LTC2937 devices allows sequencing expansion to 300 supplies. After successful sequencing and supply voltage stabilization, the reset output pulls high to initiate microprocessor or other system activity. To accommodate supply margin testing, the reset output can be disabled. Upon supply turn-off, integrated current sources are available as needed to discharge slowly decaying supplies. Configuration EEPROM supports autonomous operation without software.Applications Network Servers Data Storage Systems Telecom Equipment High Availability Computer Systems

The LT3089 is an 800mA low dropout linear regulator designed for rugged industrial applications. Key features of the IC are the extended safe operating area (SOA), output current monitor, temperature monitor and programmable current limit. The LT3089 can be paralleled for higher output current or heat spreading. The device withstands reverse input and reverse output-to-input voltages without reverse current flow.The LT3089?s precision 50?A reference current source allows a single resistor to program output voltage to any level between zero and 34.5V. The current reference architecture enables load regulation to be independent of output voltage. The LT3089 is stable with or without input and output capacitors.The output current monitor (IOUT/5000) and die junction temperature output (1?A/?C) provide system monitoring and debug capability. In addition, a single resistor programs current limit.Internal protection circuitry includes reverse-battery and reverse-current protection, current limiting and thermal limiting. The LT3089 is offered in the 12-lead 4mm ? 4mm DFN and 16-lead TSSOP (both with exposed pad for improved thermal performance), and 7-lead DD-Pak power package.Applications All Surface Mount Power Supply Rugged Industrial Power Supply Post Regulator for Switching Supplies Low Output Voltage Supply Intrinsic Safety Applications

The LTC2345-16 is a 16-bit, low noise 8-channel simultaneous sampling successive approximation register (SAR) ADC with differential, wide common mode range inputs. Operating from a 5V low voltage supply and using the internal reference and buffer, each channel of this SoftSpanTM ADC can be independently configured on a conversion-by-conversion basis to accept ?4.096, 0V to 4.096V, ?2.048V, or 0V to 2.048V signals. Individual channels may also be disabled to increase throughput on the remaining channels.The wide input common mode range and 102dB CMRR of the LTC2345-16 analog inputs allow the ADC to directly digitize a variety of signals, simplifying signal chain design. This input signal flexibility, combined with ?1.25LSB INL, no missing codes at 16 bits, and 91dB SNR, makes the LTC2345-16 an ideal choice for many applications requiring wide dynamic range.The LTC2345-16 supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces. Between one and eight lanes of data output may be employed in CMOS mode, allowing the user to optimize bus width and throughput.Applications Programmable Logic Controllers Industrial Process Control Medical Imaging High Speed Data Acquisition

Demonstration circuit 1381A is a Low Quiescent Current, Dual Output Synchronous Buck Converter featuring the LTC3857EUH/LTC3858EUH. The DC1381A provides 3.3V/5A and 8.5V/3A from a wide input voltage range of 4.5V to 36V, making it suitable for automotive or other battery fed application where low quiescent current is important. Two versions of the board are available. DC-1381A-A is for the LTC3857EUH, while the DC1381A-B is for the LTC3858EUH. The LTC3857EUH offers lower quiescent current and smaller burst mode ripple, while the LTC3858EUH offers latch-off protection and increased burst mode efficiency.

Demonstration circuit DC1385A features the LTM4614EV, the high efficiency, high density power module with dual 4A switch mode outputs. In the default configuration, the two outputs share the same input supply, which ranges from 2.375V to 5.5V, however each regulator may have its own input supply simply by removing a resistor. The device is configured for 1.2V and 1.8V outputs. Derating is necessary for certain VIN, VOUT, and thermal conditions.

Demonstration circuits 1387A-A and A-B are Ultralow Power Boost Converters with Output Disconnect featuring the LT8410 and LT8410-1. Both versions convert a 3V-10V source. The -A version supplies 1.6mA at 3VIN and the -B supplies 0.5mA. Both versions feature a low noise variable off-time and variable peak current control scheme, integrated Schottky diode and output disconnect function, ultralow quiescent current, built-in soft-start and overvoltage protection.
