Dual Output, Two-Function DC/DC µModule: LTM8049

LTM8049 Linear Technology introduces the LTM8049, a dual output, two-function DC/DC µModule® (power module) regulator in 15 mm x 9 mm x 2.42 mm BGA package. One function is SEPIC (single-ended primary-inductor converter) in which the output voltage is regulated while the input voltage can vary to be less, equal or more than the value of the output voltage.

Wideband Gain Block Amplifier: LTC6433-15

LTC6433-15Linear Technology announces the LTC6433-15, a wideband 15 dB gain block amplifier offering outstanding linearity of 47 dBm OIP3 (output third order intercept) and 3.22 dB noise figure at 150 MHz. The amplifier has excellent OP1dB (output 1dB compression point) of 19.2 dBm. The LTC6433-15 is uniquely different from other gain block amplifiers that are typically built using GaAs or pHEMT processes. These FET technologies have high 1/f noise corners on the order of 20 to 30 MHz.

Linear Tech introduces dual output boost + buck synchronous DC/DC controller

Linear Technology Corp. introduces the LTC7813, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. When cascaded, its independent step-up (boost) and step-down (buck) controllers regulate the output voltage from an input voltage that can be above, below, or equal to the output voltage, including during an automotive load dump or cold crank.

Low Quiescent Current Synchronous DC/DC Controller: LTC7813

LTC7813Linear Technology Corp. introduces the LTC7813, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. The LTC7813 operates from an input voltage of 4.5 to 60 V during start-up and maintains operation down to a 2.2 V input after start-up. The boost converter can produce an output voltage up to 60 V and the buck converter produces an output voltage ranging from 0.8 to 60V with the entire system achieving an efficiency as high as 98%.
