Analog Devices announces the LTC7000/-1, a high speed, high side N-channel MOSFET driver that operates up to a 150 V supply voltage. Its internal charge pump fully enhances an external N-channel MOSFET switch, allowing it to remain on indefinitely...

My lower-midrange Hubsan X4+ FPV drone got stuck in a tree in the middle of winter. We managed to knock it down a couple of months ago, while there was still lots of snow to cushion the fall. After weathering the elements for over a month, it appeared to be mostly fine, except...

The Optoelectronics group of Vishay Intertechnology introduced a new high sensitivity proximity and ambient light sensor that combines long distance proximity detection up to 1.5 m with Filtron™ technology in a compact 8 mm by 3 mm by 1.8 mm surface-mount package. The Vishay Semiconductors VCNL4200 three in one sensor...

Since the LED's invention more than 40 years ago, its emission efficiency has steadily increased, and, although it may surprise you, the increased conversion efficiency works in two directions. Certain bright, efficient LEDs, such as Avago Technologies HLMP-EG30-NR000, a red emitter molded in clear encapsulation, also exhibit significant photovoltaic action...

Analog Devices announces the LTC7801, a high voltage nonisolated synchronous step-down switching regulator controller in compact 24-lead packages that drives an all N-channel MOSFET power stage. Its 4 V to 140 V (150 V abs max) input voltage range is designed to operate from a high input voltage source or from an input that has high voltage surges, eliminating the need for external surge suppression devices...

IXYS Integrated Circuits Division announces the immediate availability of the IX4340 low-cost Dual 5 A Gate Driver IC. The IX4340 features two high current outputs, both capable of sourcing and sinking up to 5 A. Both outputs have an absolute maximum voltage rating of 20 V. With matched propagation delays, the identical output drivers can be connected in parallel for higher current applications...

This Design Idea has proved as useful as it is simple. With just three or four components, it allows the monitoring of current from microamps to well over 100 mA in a single range...

Ampleon announced the launch of a multi-purpose 20 Watt single-stage RF power amplifier driver transistor. The BLP9G0722-20G is a cost-effective 28 V LDMOS device that targets a wide range of applications from 0.4 to 2.7 GHz...

When it comes to the venerable 555 timer, Paul Rako agrees with Bob Pease – avoid using it if your application demands any kind of precision...

Analog Devices announces the LTC3636 and LTC3636-1 are high efficiency, 4 MHz synchronous dual output buck regulators that incorporate a unique constant frequency/controlled on-time, current mode control scheme with phase lockable switching frequency...
