Linear Technology Corporation introduces the LTC3810H-5, a high input voltage synchronous step-down DC/DC controller with guaranteed specifications for junction temperatures as high as 150°C.

Linear Technology has announced the LTC3786, a synchronous step-up DC/DC controller that replaces the boost diode with a high efficiency N-channel MOSFET. This eliminates the heat sink normally required in medium to high power boost converters. In applications where the input voltage may exceed the regulated output voltage, the LTC3786 is able to keep the synchronous MOSFET on continuously so that the output voltage follows the input voltage with...

Linear Technology has introduced the LTC3891, a high voltage synchronous step-down DC/DC controller that draws only 50µA in standby mode with the output in regulation. The 4V to 60V input supply range is designed to protect against high voltage transients, continue operation during automotive cold crank and cover a broad range of input sources and battery chemistries. The output voltage can be set from 0.8V to 24V at output currents up to 20 amp...

TDK-Lambda’s EFE Series of embedded frontend power supplies is said to deliver industry leading power density, high efficiency and enhanced reliability. The first products in the range are the 300W EFE-300 and the 400W EFE-400 single output supplies that deliver 133% peak power capability for 10 seconds and offer a class leading efficiency of up to 90%.

TDK-Lambda UK, expands the HFE series of 1U high, single output AC-DC hot swap, front end power supplies with the addition of 2.5kW models. Offering an industry leading power density of 29W/in3, the HFE2500 power supply is equally well-suited for 2.5kW bulk power and Distributed Power Architecture (DPA) applications. All HFE2500 models feature full current-sharing capabilities and internal ORing MOSFET for isolation to support hot-swap and redund...

Rapid Electronics has expanded its range of ST linear ICs and discrete devices with the introduction of a brand new range of IGBTs, increased coverage of surface mount package options and additions to its MOSFET ranges.

The A1172 from Allegro MicroSystems Europe is an ultra-sensitive micropower Hall-effect switch with complementary, latched digital outputs and omnipolar magnetic actuation. The new device features operation at low supply currents and voltages, making it ideal for battery-operated electronics. The combination of a low operating supply voltage (1.65 V to 3.5 V) and a unique clocking algorithm assists in reducing the average operating power consumpt...

The new A3904 from Allegro MicroSystems Europe is said to be the first in a series of voice-coil motor driver ICs designed for camera auto-focus and zoom applications. Featuring a built-in I2C serial interface for precise high-speed digital programming with only two control lines, the new device features an operating voltage range of 2.4 to 5.5 V and a maximum output current of 127 mA. Output current is programmed via the I2C interface in 500 µA...

Linear Technology has announced the LT3748H, a high input voltage isolated flyback DC/DC controller with guaranteed operation for junction temperatures as high as 150°C. This device significantly simplifies the design of an isolated DC/DC converter since there is no requirement for an opto-isolator, third winding or signal transformer for feedback, as the output voltage is sensed from the primary-side flyback signal. The LT3748 operates over a 5...

Linear Technology has announced the LTC3600, a 1.5A, high efficiency, synchronous buck regulator that can be easily paralleled for higher current applications and is adjustable down to 0V with a single resistor. This new switching regulator architecture uses a 50µA current reference, combined with a single resistor to set the output voltage. This unique design enables easy current sharing between multiple regulators, setting the output voltage f...
