Offline Switcher ICs Enable Compact and Lightweight Notebook Adapters
Power Integrations has announced a new, ultra-low-profile package for its popular TOPSwitch-HX family of AC-DC power conversion ICs. This small new package combined with the best-in-class efficiency and high operating frequency of TOPSwitch-HX enables remarkably slim, compact, and lightweight power supplies from 20 to 100 watts. Applications include adapters for notebook computers, as well as power supplies for LCD monitors and flat-panel TVs, in...
Power Integrations New HiperLCS High-Frequency LLC Converter IC Family Maximizes Power Supply Efficiency, Minimizes Footprint
Power Integrations introduced HiperLCS, a family of high-voltage LLC power supply ICs that incorporate the controller, high- and low-side drivers, and both MOSFETs into a single low-cost package. Highly integrated HiperLCS ICs offer the flexibility to optimize designs either for high efficiency – with a maximum efficiency of better than 97% – or for size, by leveraging high-frequency operation (up to 750 kHz) to minimize transformer size and ...
Power Integrations Announces Strategic Investment in SemiSouth Laboratories
Power Integrations today announced a strategic investment in SemiSouth Laboratories, Inc., a Mississippi-based manufacturer of high-voltage silicon-carbide (SiC) semiconductor devices. Power Integrations’ commitment of $30 million, which includes an equity investment in SemiSouth, a technology license and other financial commitments, will help drive the continued expansion of SemiSouth’s SiC fabrication facility and spur continued growth of c...
Analog Devices Introduces Industry’s First 3-GHz HDMI Receiver
Analog Devices introduced the industry’s first 3-GHz (gigahertz) HDMI receiver for advanced television solutions. This new dual input receiver incorporates HDMI (High-Definition Multimedia Interface®) specification version 1.4a support 3D display resolutions and extended colourimetry.
20V Step-Down DC-to-DC Non-Synchronous Regulators Simplify Intermediate Power Bus and Point-of-load Power Designs
Analog Devices, introduced the ADP2300 and ADP2301 dc-to-dc switching regulators, the most recent in their growing portfolio of integrated power management switching regulators. The new 20V 1.2A (amp) step-down, dc-to-dc switching regulators integrate a high-side MOSFET that delivers power conversion efficiencies greater than 90 percent. The new regulators also feature internal loop compensation, integrated soft-start circuitry and bootstrap diod...
Multilayer ceramic transient voltage suppressors target ESD protection for CMOS, Bipolar and SiGe devices
StaticGuard multilayer ceramic transient voltage suppressors from AVX Corporation, a leading manufacturer of advanced passive components, are designed to address ESD protection for CMOS, Bi-polar and SiGe based devices. The voltage suppressors meet 15 kV ESD pulse (air discharge) per IEC 1000-4-2, Level 4, generating less than 20 millijoules of energy. It is particularly important to protect ICs against ESD as the typical failure voltage for CMOS...
Multilayer varistors from AVX protect antennas and RF amplifiers from transients and ESD
AntennaGuard multilayer ceramic transient voltage suppressors from AVX Corporation, a leading manufacturer of advanced passive components, target RF-antenna and RF-amplifier protection. These devices are zinc-oxide (ZnO) based, multilayer ceramic chips in 0402 and 0603 sizes and feature non-linear, bi-directional voltage-current characteristics similar to back-to-back Zener diodes and an EMC (electromagnetic compatibility) capacitor in parallel.
Varistors from AVX reduce component count for ESD protection in CAN applications
CAN Series varistors from AVX Corporation are specifically designed to provide ESD protection in controlled-area-network (CAN) applications, predominantly in automotive electronics. The zinc-oxide (ZnO) based, multilayer ceramic varistors feature non-linear, bi-directional voltage-current characteristics similar to back-to-back Zener diodes and an EMC (electromagnetic compatibility) capacitor in parallel. This “equivalent” capacitor e...
Varistor provides enhanced protection and reduces component count
The latest surface-mountable AVX CANBus varistors replace three components typically used to protect against transient voltage spikes: two back-to-back Zener diodes and an EMC capacitor in parallel.
AVX launches industry’s first 63V and 75V SMD Polymer Tantalum capacitors for high voltage applications
AVX Corporation has developed the industry’s first 63V and 75V single-anode tantalum polymer capacitors. Part of the TCJ Series polymer tantalum capacitors, these new surface mount devices (SMDs) deliver high capacitance, high voltage and low ESR values in a small case size.
