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, […]

90-A dc-dc converter delvers high power density at 178A/in2
With IT and networking technologies continue to pack more features and processing capacity into smaller packages, printed circuit and wired board space are at more of a premium than ever before. For power engineers and board designers, that can mean less board space available for required power components. ABB is helping to free up valuable […]
500-W step-down dc-dc converter sits in 1/16th brick footprint
TDK Corporation announces the introduction of the 500W rated i7A non-isolated DC-DC converters. Capable of operating from an input voltage of 18V to 60V, the step-down converters deliver an output voltage that can be adjusted from 3.3 to 24V with an output current of up to 33A. The series is designed to be used in […]
Eval kits speed GaN power device uses in industrial motors, energy storage systems, inverters
GaN Systems announced the availability of four new integrated power module evaluation kits: 100V Driver GaN DC/DC Power Stage Module, 650V 150A Half-Bridge IPM, 650V 150A Full-Bridge Module, and Driver, and 650V 300A 3-Phase Module and Driver. These modules are designed to be easy to use and evaluate performance in high power applications such as traction […]
SMD Metal-Foil-on-Ceramic resistors boast high surge tolerance, low self-heating
TT Electronics announced the introduction of its Metal Foil Chip (MFC) resistors. The MFC series uses metal foil on ceramic technology, which combines the heat spreading properties of a ceramic substrate with the surge tolerance of a bulk metal alloy resistance element. This, in turn, offers lower self-heating levels than thick-film or metal strip resistors and better surge tolerance than thick-film options, making these resistors particularly well-suited for automotive, industrial, and medical […]
