I recently had the chance to review a new RF signal generator from Trinity Power Inc. Their model TPI-1001-B is much more than just a mere synthesizer. This improved model also includes several modulations as well as scalar analysis (a "poor man's" network analyzer). The product (Figure 1) is available from RF design consultant, Robert Yarbrough … [Read more...]
New Line of Flat Wire Inductors Introduced
ITG Electronics, a leading manufacturer of inductors and transformers in business since 1963, now offers a range common footprints as well as custom flat wire inductors for high power density and high frequency switching. As the name suggests, flat wire inductors utilize a flattened, rectangular cross section, copper wire instead of a traditional, circular cross section, … [Read more...]
New Nanocrystalline Common Mode Chokes
ITG Electronics, a leading manufacturer of inductors and transformers in business since 1963, now offers a range of Nanocrystalline Common Mode Chokes which deliver higher power ratings in a small size. Nanocrystalline material gets its name from its production process. A stream of molten metal is rapidly cooled and locks in the amorphous high energy structure. The resulting … [Read more...]
Extended Range of PTC Inrush Current Limiters
TDK Corporation has extended its range of EPCOS PTC-based inrush current limiters. The four new versions of the B5921*J0130A020 series with plastic housing are designed for voltages from 280 V AC to 560 V AC, offer rated resistances from 22 Ω to 100 Ω at 25 °C and have a heat capacity of up to 2.3 J/K. They are UL approved and are qualified to AEC-Q200. The B594* and B597* … [Read more...]
LED Driver for Automotive Applications Minimizes EMI
Linear Technology has announced the LT3932, a monolithic, synchronous, step-down DC-DC converter with internal 36V, 2A power switches and an internal PWM generator. Its fixed frequency, peak current mode control accurately regulates current within ±1.5% for strings of up to 2A LEDs. Its integrated PWM generator offers a 128:1 dimming ratio. The device’s 3.6V to 36V input … [Read more...]
Input Filters – The Key to Successful EMC Validation
Co-authored by: Ranjith Bramanpalli & Steffen Schulze Würth Elektronik INTRODUCTION Input filters are today as ever a requisite factor for successful EMC validation of switching controllers, irrespective of the size of the AC component involved. Switching controllers create conducted EMC interferences due to AC components in their lines, independent of their individual … [Read more...]
Top Three EMI and Power Integrity Problems with On-Board DC-DC Converters and LDO Regulators
Co-authored by: Kenneth Wyatt and Steve Sandler INTRODUCTION Modern devices are continuing a long-term trend of squeezing more electronics into smaller packages, while also increasing system performance, data rates and operating efficiency. Higher efficiencies are often achieved by implementing faster silicon MOSFETs or even faster eGaN FETs while size is reduced by … [Read more...]
