Synchronous dc/dc buck converter optimized for noise-sensitive apps
The STMicroelectronics L7983 is a compact, 3V-60V, 300mA synchronous DC/DC buck converter with flexible, dynamic-mode selection to satisfy noise-sensitive applications and maximize efficiency at light load. Special ST innovations engineered into the L7983 allow control of the low-side power MOSFET to provide a low-noise mode (LNM) with constant switching frequency and an alternative low-consumption mode (LCM). In LCM, […]
SMD MOSFETs cut losses in motor drive applications
Infineon Technologies AG supports the robotics and automation industry in implementing maintenance-free motor drive inverters. By introducing the new CoolSiC MOSFET with.XT interconnection technology in a 1200 V optimized D 2PAK-7 SMD package, passive cooling becomes possible. Up to 80 percent loss reduction compared to a silicon-based solution eliminates the need for cooling fans and […]
Rad-hard motor controller IC incorporates position sensing for satellites
The need to reduce size, weight, and power on satellites and other space systems continue to challenge the aerospace market. Combining more than 20 commonly used functions into a single chip, Microchip Technology Inc. announced the LX7720 radiation-hardened mixed-signal motor controller, the latest addition to its Space System Manager (SSM) product family. As the industry’s first highly […]
