Linear Technology Corp. introduces the LT4320, an ideal diode bridge controller for 9 to 72 V systems that replaces each of the four diodes in a full-wave bridge rectifier with a low loss N-channel MOSFET to significantly reduce the power dissipation and increase available voltage. The controller operates from DC to 600Hz.
Linear Technology Corporation announces the LT3995, a 3A, 60V step-down switching regulator, requiring only 2.7 µA of quiescent current. The LT3995’s 4.3 to 60 V input voltage range makes it ideal for automotive, commercial vehicle, avionic and industrial applications. Its internal 4.7 A switch can deliver up to 3 A of continuous output current to voltages as low as 1.2 V.
Linear Technology Corp. announces the LT3055, a high voltage, low noise, low dropout voltage linear regulator offering precision, programmable current limit and diagnostic capability. The device delivers up to 500 mA output current with a 350 mV dropout voltage at full load. The LT3055 features a wide 2 to 45 V input voltage range, delivering adjustable output voltages from 0.6 to 40 V.
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.
