Toshiba Launches High-Current 4-Channel H-bridge Motor Driver IC
14.09.2017 · News
Toshiba Electronics Europe announced the launch of a new 4-channel H-bridge motor driver IC that delivers up to 3.5 A and 40 V. The TB67H452FTG is intended for the significant and rapidly growing consumer market...
Raspberry Pi GPIO Explained. Part 1
The Raspberry Pi is a computer, and from a connections point of view it doesn’t look much different to a normal desktop computer. It has USB ports for connecting a keyboard and mouse, and a video output port for connecting up a display. Because it is more compact and lower cost than a large desktop PC, it becomes possible to use the Raspberry Pi or other small single board computers as they are known, for many scenarios where a desktop or laptop PC would not be feasible...
150V Synchronous Buck-Boost Controller Eliminates Surge Protection Devices & Delivers Up to 99% Efficiency
14.09.2017 · News
Analog Devices announces the LTC3779, a high efficiency (up to 99%) 4-switch single inductor synchronous buck-boost DC/DC controller that operates from input voltages above, below or equal to the regulated output voltage. Its 4.5 V to 150 V input voltage range is designed to operate from a high input voltage source or from an input that has high voltage surges...
Switching regulator forms constant-current source
13.09.2017 · Circuits
Many applications require current sources rather than voltage sources. When you need a high-current source, using a linear regulator is inadvisable, because of the high power dissipation in the series resistor. To solve the wasted-power problem, you can use a switch-mode regulator...
SII Semiconductor has launched the production of economical Step-Down converters for portable and mobile devices

Analog Devices announces the LTC7004, a high speed, high side N-channel MOSFET driver that operates up to a 60 V supply voltage. Its internal charge pump fully enhances an external N-channel MOSFET switch, enabling it to remain on indefinitely...
Inverting sample-and-hold amplifier requires no external resistors
07.09.2017 · Circuits
Many applications require a sampling circuit whose output is inverted with regard to the respective sample of an input signal. A simple approach is a cascade of a common noninverting sample-and-hold amplifier and an inverting amplifier. A classic inverting amplifier is an op amp with voltage feedback from two resistors...
