The ISL81801 buck-boost controller acts as a “UPS on a chip” by enabling bidirectional current flow (forward or reverse) using constant-voltage and constant-current regulation. This allows a battery or supercapacitor to be charged and discharged using a single controller and power path. The ISL81801’s combination of the industry’s highest 80V buck-boost switching frequency (600 kHz) […]

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 […]
QML-V qualified 7-A PoL dc/dc converter is rad hardened
STMicroelectronics has added a QML-V qualified 7A Point-of-Load (PoL) DC/DC converter to its growing portfolio of radiation-hardened (rad-hard) integrated power products that deliver high power efficiency to satisfy the most demanding space applications. The RHRPMPOL01 is a complete PoL converter, including N-channel power MOSFET and bootstrap diode, with under-voltage, over-voltage, over-temperature, and adjustable over-current protection in a […]
12 V DC PCB relay features 50 A to 14 V DC switching capability
Fujitsu Components America, Inc. has expanded its automotive relay offering with a new 12VDC PCB relay featuring a switching capacity of 50A at 14VDC. The FBR53-HC offers a higher contact rating than its 40A FBR53-HW counterpart, yet occupies the same 12.1 x 15.5 x 13.7mm footprint and weighs the same 6g. With a maximum carrying […]
