Linear Technology announces the LTC4358, a single high voltage ideal diode controller utilizing an internal 5A MOSFET to provide a simple, low loss replacement to Schottky diodes in high current applications. The controller and 20m Ohm internal N-channel MOSFET perform the function of a low forward voltage diode. This provides a lower loss path compared to the Schottky diode that in high current applications provides higher efficiency and preserves precious board area by eliminating the need for heat sinking. The LTC4358 regulates the forward voltage drop across the internal MOSFET to ensure smooth switchover from one path to another without oscillation. A fast pull-down circuit minimizes reverse current transients in the event a power supply fails or is shorted

Linear Technology introduces the LTC2631, a family of pin- and software-compatible 12-bit, 10-bit and 8-bit DACs in a tiny TSOT-23 package, making it the smallest I2C DAC family with an internal reference on the market today. DACs in such small packages are ideal for fine tuning bias voltages in applications such as optical networking and RFID systems. The LTC2631 makes the integrated 10ppm/°C reference output available to drive the reference inputs for all other data converters on the board, while maintaining good stability over temperature.
