Analog Devices, which recently acquired Linear Technology, has announced the LT8609S, a 2A (3A Peak), 42V input synchronous step-down switching regulator. Its unique Silent Switcher2 architecture uses two internal input capacitors as well as internal BST and INTVCC capacitors to minimise the area of the hot loops.

Two new series of high-performance electrolytic capacitors manufactured by Panasonic are in stock at RS Components. Offering excellent characteristics for a wide variety of applications, the V-TC and V-TCU series of aluminium electrolytic capacitors are specialised miniaturised components offering ripple current and high capacitance.

A new micropower LED driver IC has been released by Allegro MicroSystems Europe that features an integrated Hall-effect switch. The APS13568 enables compact, elegant, reliable, and fault-tolerant LED lighting with minimal electrical engineering and low component-count and cost. A single silicon chip integrates: a micropower regulator, a Hall plate, a small-signal amplifier, chopper stabilisation, a Schmitt trigger, open drain Hall-effect switch, ...

Texas Instruments has introduced the industry’s first 2-kilowatt (kW) isolated bidirectional DC/DC converter reference design for 48 to 400V Uninterruptable Power Supplies (UPS) and energy storage systems.

Most modern power conversion topologies use switched-mode techniques for highest efficiency and smallest size and cost. Inevitably, switching noise is produced and output filters are required to minimise EMI and provide reliable operation of the power converter and load. This article looks at the effects of noise and some of the filtering techniques that can be used.

A wireless, battery-less pacemaker that can be implanted directly into a patient’s heart is being introduced by researchers from Rice University and their colleagues at the Texas Heart Institute (THI) at the IEEE’s International Microwave Symposium (IMS) in Honolulu.The internal components of a battery-free pacemaker introduced this week by Rice University and the Texas Heart Institute.

In applications from the simplest cell-phone charger to grid-tied inverters operating at hundreds of kW, power conversion schemes are used which incorporate an intermediate stage where energy is processed at DC. A ‘DC-link’ capacitor is fitted at this point to provide a low impedance path for high frequency switching currents and to provide energy storage.

Automobile safety concerns are increasing worldwide and a Tyre Pressure Monitoring System (TPMS) has proven to be a very effective way of reducing single car accidents caused by insufficient tyre pressure. Here, Nicolas Henriet, Senior RF Engineer, Sensata Technologies, describes how the company used high frequency software to enhance the design process and optimise its TPMS performance.

Analog Devices, which recently acquired Linear Technology, has announced the LTC7124, a high efficiency, 4MHz synchronous dual output buck regulator that incorporates a constant frequency, peak current mode architecture.Optional spread spectrum frequency modulation is integrated for reducing radiated and conductive EMI noise. The device can deliver up to 3.5A of continuous output current from each channel or generate a 2-phase single output up to...
