700-V switched supply targets smart meters, home automation
Expanding its portfolio of high-voltage power solutions for offline AC/DC designs, Texas Instruments (TI) (NASDAQ:TXN) introduced a 700-V switcher with the industry’s lowest quiescent current of less than 100 uA – half the power consumption of existing solutions. The UCC28880 controller integrates a 700-V power MOSFET and high-voltage current source, increasing overall energy efficiency of […]
Low-capacitance diodes help thwart ESD
Littelfuse, Inc. has introduced the low-capacitance SP3014 Series TVS Diode Array (SPA® Diodes), to provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). The SP3014 Series, which integrates two channels of low capacitance steering diodes and a zener diode, can safely absorb repetitive ESD strikes above the maximum level specified in the […]
Switching regulator fundamentals – the SEPIC converter
OK, so maybe it’s not the logical follow-on from the buck converter but nevertheless a useful converter and probably a bit more interesting than the boost converter. The SEPIC – Single Ended Primary Inductance Converter – is useful because while a buck converter allows you to step down the voltage and a boost converter allows […]
Coming in September: Sixth Annual IEEE Energy Conversion Congress and Exhibition to kick off in Pittsburgh
The Sixth Annual IEEE Energy Conversion Congress and Exhibition (ECCE 2014), “Your Bridge to a Clean and Sustainable Energy Future,” will come to Pittsburgh, Pa. Sept. 14 through 18. The event will include an expo area of about 40 exhibitors. On Tuesday Sept. 16, admission to the exhibits will be free to the public as […]
Power-Handling Software Tool Facilitates Fast Conversion to Isolas RF-Materials
Isola is pleased to announce a free Impedance and Power-Handling Calculator that predicts the design attributes for microstrips and striplines based on the designs target impedance and dielectric properties of the companys RF, microwave and millimeter-wave laminate materials. This new tool supports Isolas earlier announcement of a Design Review Service, in which its technical staff […]
Switching regulator fundamentals – the buck converter
By Chris Francis Switching regulators are everywhere – buck, boost, SEPIC, Cuk, flyback etc. They are for converting power from one voltage to another in a relatively efficient manner. Whereas with a linear regulator you might lose 50% of the power or more in heat, switching regulators can reach efficiencies of close to 100% for […]
New 2756 MHz VCO from Crystek
Crystek’s CVCO55CC-2756-2756 VCO (Voltage Controlled Oscillator) operates at 2756 MHz with a control voltage range of 0.5V~4.5V. This VCO features a typical phase noise of -116 dBc/Hz @ 10KHz offset and has excellent linearity. Output power Engineered and manufactured in the USA, the model CVCO55CC-2756-2756 is packaged in the industry-standard 0.5-in. x 0.5-in. SMD package. […]
Low Resistance Values Ideal for Portable Consumer Electronics
The CSRF Series is a surface mount current sense resistor series that utilizes foil on ceramic carrier technology. This structure allows for very low resistance values in small case sizes while maintaining good TCR. The 0402 size is available in the popular 10 milliohm value, while the 0603 size is available in values down to […]
