Vishay – Generating isolated supplies for industrial applications using a synchronous buck regulator in an isolated buck topology


Industrial power applications typically require a high input voltage. Standard voltage rails are 24V, 36V and 48V. The DC- DC buck switching regulators and controllers used to power the circuits in industrial applications are required to provide solid, reliable performance and to withstand the effects of noise, power surges and outages. It is common for […]

Vishay – New synchronous buck regulators offer high efficiency over wide input-voltage range


The SiC46x series synchronous buck regulators from Vishay operate over a very wide input-voltage range of 4.5V to 60V and provide an output current of up to 10A with high conversion efficiency. The SiC46x regulators include integrated high- and low-side N-channel trench power MOSFETs, and operate at an adjustable switching frequency of up to 2MHz. […]

Vishay – Rectifiers save space and improve thermal performance in consumer devices


Vishay Intertechnology has introduced a new family of surface-mount Trench MOS Barrier Schottky (TMBS) rectifiers in a compact package, the eSMP® series SlimDPAK, or TO-252AE, package style. The SlimDPAK rectifiers offer the advantages of a lower profile and better thermal performance than comparable devices in a DPAK (TO-252AA) package. While the new devices are footprint-compatible […]

Ideal for both analogue and digital signal switching in space-constrained consumer, medical and industrial applications, the DG2788A offers improved resistance flatness, signal integrity, parasitic capacitance and bandwidth. While competing devices with similar […]

Vishay – Energy-storage capacitors offer high energy density and rapid charging and discharging


Vishay Intertechnology has announced an extension to its 220 EDLC ENYCAPTM series of Electrical Double- Layer Capacitors (EDLC) for use in energy harvesting and power back-up applications. Available in Power and Energy versions, the ENYCAP devices now offer a wider range of capacitance values ranging from 15F to 60F, in eight small case sizes ranging […]

Vishay – How to implement a reliable, long-life DC link capacitor bank in high-voltage power circuits


The functional requirement for an electric vehicle’s fixed battery charger is to charge the battery in the shortest possible time, while minimising battery ageing and maintaining safe operation. This requires accurate control of high amounts of power: depending on battery capacity, an overnight recharge can require a charger capable of providing up to 30kW of […]
