Linear Technology announces the LTC3639, a 150V input-capable synchronous buck converter that delivers up to 100mA of continuous output current. It operates from an input voltage range of 4.5V to 150V, eliminating the need for an external transient suspension device. The LTC3639 utilizes internal synchronous rectification and a programmable peak current-mode design to optimize efficiency over a broad range of output currents.

Linear Technology Corp. introduces the LTC4290/LTC4271 isolated 8-port power source equipment (PSE) controller chipset designed for use in IEEE 802.3at (PoE+) Type 1- and Type 2-compliant Power-over-Ethernet (PoE) systems. The LTC4290/4271 provides 8 independent PSE channels for simpler lower component count designs, reduced board space and ultimately reduced total solution costs.

Linear Technology introduces the LTM9013, a wideband RF-to-digital µModule® (micromodule) receiver that includes a high performance dual 14-bit, 310Msps analog-to-digital converter (ADC), a high IIP3 I/Q demodulator, two variable gain amplifiers, and 300MHz lowpass filters. The LTM9013’s quadrature sampling architecture enables acquisition of up to 300MHz of signal bandwidth with IMD3 performance of 66dB across the entire band.

The LTC3621 is a high efficiency, 17V input capable synchronous buck regulator from Linear Technology that delivers up to 1A of continuous output current to outputs as low as 0.6 V. Synchronous rectification delivers efficiencies as high as 95% while Burst Mode® operation requires only 3.5 µA of no load quiescent current.

Linear Technology Corp. introduces the LTC6957, a DC to 300 MHz dual output buffer/driver/logic translator, ideal for converting sine waves into low phase noise logic level signals. Prior solutions were unable to perform this conversion without introducing a significant amount of jitter.

Linear Technology Corp. announces the H-grade version of the LTC3722-1, a phase-modulated full bridge DC/DC controller with adaptive or manual zero voltage switching (ZVS). The device’s ZVS delay control and adjustable synchronous rectification timing optimize efficiency while reducing transformer size and electromagnetic interference, making it well suited for isolated high power applications of up to several kilowatts.

Linear Technology Corp. announces the LT3007, the latest member in a family of high voltage, micro power, robust PNP-based LDOs, featuring an ultralow 3µA quiescent current. The LT3007’s high input voltage capability, spanning 2.0 to 45 V with an adjustable output voltage ranging from 0.6 to 44.5 V, enables operation in a wide variety of application spaces.

Linear Technology announces the LTC6995, a simple, accurate low frequency clock uniquely configurable for long duration power-on reset and watchdog timer applications. The LTC6995 is the latest part in the TimerBlox® family of versatile silicon timing devices, which combines an accurate programmable oscillator with precision circuitry and logic.

Linear Technology announces the LTC3129, a synchronous buck-boost converter that delivers up to 200 mA of continuous output current from a wide variety of input sources including single or multiple-cell batteries as well as solar panels and supercaps. Its 2.42 to 15 V input range and 1.4 to 15.75 V output range provide a regulated output with inputs above, below or equal to the output.

Linear Technology Corp. announces the LT3030,a dual low noise, low dropout regulator with independent inputs and independent shutdown control for each channel. The device delivers continuous output current up to 750 mA on one channel and 250 mA on the other channel, with a low dropout voltage of only 300 mV at full load.
