The LTC4291/LTC4292 provides 4 independent PSE ports comprised of 2 channels each, ensuring fully compliant support for the next generation of IEEE 802.3bt powered devices (PDs). The […]
Off-line converters incorporate logic-level primary MOSFET for efficient 5-V output
The VIPer11 off-line converter with embedded 800V avalanche-rugged MOSFET from STMicroelectronics enables equipment makers to design tougher auxiliary power supplies and power adapters. Its 26Vdc drain-start voltage allows an ultra-wide line input voltage range and it enhances flexibility in numerous consumer and industrial applications. The logic-level primary MOSFET enables the VIPer11 to operate with a wide supply […]
Voice-coil actuators, Part 1: Principle basics
When designers need a modest amount of motion and power, they naturally think of a motor. That makes sense since there’s often a brushed, brushless, or stepper motor that can meet the objectives, sometimes with some necessary add-on gearing. Or they may think of a solenoid for impact-type linear motion. This FAQ looks at another […]
Power detectors span 5 – 44 GHz range, support 30 dB dynamic range
