Linear Technology announces the LTC3646, a 40 V input capable synchronous buck converter than can deliver up to 1 A of continuous output current from a 3 mm x 4 mm DFN-14 (or thermally enhanced MSOP16) package. It operates from an input voltage range of 4 to 40 V, making it ideal for automotive and industrial applications that require high voltage input capability.

Linear Technology announces the LT3761, a 60 V DC/DC controller designed to operate as a constant-current source and constant-voltage regulator. Its internal PWM dimming generator makes it ideal for driving high current LEDs, but it also has features making it suitable for charging batteries and super-capacitors.

Linear Technology Corp. announces the LTC3375, a highly-integrated general-purpose power management solution for systems requiring multiple low voltage power supplies. The device features eight independent 1A channels with I²C control, flexible sequencing and fault monitoring in a compact QFN package.

Linear Technology Corp. introduces the LTC3864, a high voltage step-down DC/DC controller that draws only 40 µA quiescent current in standby mode with the output enabled in Burst Mode^® operation. The 3.5 to 60 V input supply range is designed to protect against high voltage transients, to operate continuously during automotive cold crank and covers a broad range of input sources and battery chemistries.

Linear Technology Corporation introduces the LTC4226, a dual Hot Swap™ controller, enabling safe board insertion into live 4.5 to 44 V backplanes. The LTC4226 controls external N-channel MOSFETs to gently power up the board, avoiding sparks, connector damage and system glitches. A dual rate fault timer protects the MOSFET and system from long or damaging overcurrents.

Linear Technology announces the LT3763, a synchronous buck LED driver controller that delivers over 300 W of LED power. Its 6 to 60 V input voltage range makes it ideal for a wide variety of applications, including automotive, industrial and architectural lighting. Similarly, its output voltage can be set from 0 to 55 V, enabling it to drive a wide range of LEDs in a single string.

Linear Technology Corp. announces the LTC3122, a 3 MHz current-mode, synchronous boost DC/DC converter with integrated output disconnect. Its internal 2.5A switches deliver output voltages as high as 15 V from an input voltage range of 1.8 V at start-up (0.5 V when running) to 5.5 V, making it ideal for battery or standard 3.3 V and 5 V power sources.

Linear Technology Corp. introduces the LTM4641, a 4.5 to 38 V input, 0.6 to 6 V output, 10A step-down µModule® regulator with comprehensive electrical and thermal protection for loads such as processors, ASICs and high-end FPGAs. The LTM4641 µModule regulator monitors input voltage, output voltage and temperature conditions.

Linear Technology Corporation introduces the LTM2883, a 6-channel SPI/Digital or I² C digital µModule® isolator with triple rail regulated power for 3.3 and 5 V systems. In industrial systems applications, ground potentials can vary widely, often exceeding the tolerable range, which can interrupt communications or even destroy components.
