Common-mode filters handle high-temp automotive apps
TDK Corporation announced the development of its KCZ1210AH series of miniaturized common-mode filters for automotive applications. The series is extremely compact, measuring 1.25 (L) x 1.0 (W) x 0.5 mm (H), which contributes to a smaller footprint on the substrate and provides a noise control function for different transmission signal lines for automobiles. With an […]
What is a Bode plot?
A Bode plot represents the gain and phase of a feedback system as a function of frequency. It was developed by Hendrik Wade Bode in the 1930s and reflects the system’s frequency-domain behavior. He invented it while at Bell Labs to help design stable amplifiers with the feedback needed in telephone networks. The graphical design […]
AC challenges with inductors
To get good performance from inductors in power supplies, you need to be careful about the AC characteristics. Physical inductors are complex structures, not ideal components. And the AC challenges with inductors are growing due to the higher operating frequencies of power supplies using silicon carbide (SiC) and gallium nitride (GaN) power switches. This FAQ […]
Small, high-brightness RGB LEDs boast improved color mixing
Upward-lighting multicolor LEDs in the CL-V501 Series have improved color mixing, come in a small package, and exhibit high brightness. Multicolor LEDs have three dies of RGB (red, green and blue) in one package. This lets them generate various colors, including white, and are used for illumination or as indicators in many kinds of products […]
DC voltages, AC voltages and Stiff voltages
At its most basic level, voltage is a simple concept. Voltage, also referred to as electric potential difference or electromotive force (emf), is the difference in electric potential between two points. In the International System of Units (SI), one Volt equals one Joule of work per Coulomb of charge. In practical applications, voltage is simple, […]
RF amplifiers optimized for harsh operational conditions
Ampleon has announced a further expansion to its portfolio of next-generation amplifier ICs. These devices are based on the company’s Advanced Rugged Technology (ART). Thanks to the heavy-duty design employed, they are capable of dealing with the harshest of operational conditions. With 1400W and 1600W ratings, the devices in the new ART1K6x series operate over […]
Single-chip driver handles high frequency switching of GaN enhancement-mode FETs
STMicroelectronics’ STDRIVEG600 half-bridge gate driver has a high current output and 45ns propagation delay, closely matched between high-side and low-side outputs, to handle high-frequency switching of GaN enhancement-mode FETs. Also suitable for driving N-channel silicon MOSFETs at up to 20V, the STDRIVEG600 allows the flexibility to apply up to 6V gate-source voltage (VGS) on GaN […]
