Intersil, a subsidiary of Renesas Electronics Corporation introduced five synchronous buck regulators that step-down 12 V rails to point-of load inputs as low as 0.6 V for MCUs, FPGAs, memory and peripheral I/Os. The newest members of the ISL850xx family consist of the ISL85014, ISL85012, ISL85009, ISL85005A and ISL85005 buck regulators...
Class B amplifier has automatic bias
06.21.2017 · Circuits
B amplifiers are prone to crossover distortion, which occurs in the output stage in which conduction transfers from one transistor to the other. To prevent crossover distortion, a bias current must flow in both transistors simultaneously. The bias current prevents both transistors from turning off in the transition region. Classic bias circuits keep a constant dc polarization voltage between the bases of the two transistors...
2.7V to 38V/500mA Low Noise Buck-Boost Charge Pump Saves Space and Reduces EMI

The other day, while juggling a pile of recorded and blank videotapes for my VCR (please, no snickering that I still use a VCR!) I realized that what I would really like is a video recorder that combines the virtues of removable storage modules with modern digital technology...
Analog Devices' Small Isolated Gate Drivers Deliver Solutions for Next Generation Power Switch Technology
06.20.2017 · News
Analog Devices announced small form factor isolated gate drivers designed for the higher switching speeds and system size constraints required by power switch technologies such as SiC and GaN, while still providing reliable control over switching characteristics for IGBT and MOSFET configurations...
Build an adjustable high-frequency notch filter
06.19.2017 · Circuits
Although you can obtain universal, resistor-programmable switched-capacitor filters that are configurable as notch filters, most cannot operate at bandwidths higher than 100 kHz. Further, the typically 16- to 20-pin packages do not include a continuous-time, antialiasing filter to prevent spurious signals from appearing at the output...
60V Low IQ Synchronous Step-Down Controller Operates at Up to 2.25MHz for High Power Density
