Fuel gage IC eliminates need to characterize battery drains
Developers of portable devices now have an easier way to design in the most accurate and low power host-side battery gauges with the MAX17055 ModelGauge™ m5 from Maxim Integrated Products, Inc. Traditionally, fuel gauges required extensive characterization of each battery type, used in specific applications, for attaining good performance. This meant the customer had to perform complicated […]

What is a charge pump and why is it useful? (Part 1)
It’s a very common challenge in circuits to need to convert an available DC source to a lower or higher voltage. For the high-to-low conversion, one option to use a low dropout regulator (LDO), but how to easily transform a lower voltage into a higher one? For AC voltages, the answer is well-known: use a […]
LED driver ICs offer 1W of power savings in LED boost circuit
Peregrine Semiconductor Corp., a Murata company, announces Arctic Sand’s new product family—the ARC3C family of LED driver ICs. The ARC3C product line targets the fast growing, ultra-high-definition (UHD) LCD displays market for notebook computers, Ultrabooks and 2-in-1 convertibles. The products deliver dramatic improvements in power conversion efficiency, while achieving the lowest “z” height profile and smallest […]
2-W fusable wire-wound power resistors save PCB space
TT Electronics, a global provider of engineered electronics for performance critical applications, today launched its ULWP2R range of fusible wirewound resistors. By combining the functions of a fuse and a line input resistor in a single, vertical radial formed component the resistors save valuable PCB space. The UL recognised, 2W rated power resistors are aimed […]
Low-profile SMD capacitors handle 900 V
TDK Corporation has extended the CeraLink™ series with two low-profile (LP) types designed for a rated voltage of 900 V DC. The SMT capacitors have a capacitance of 0.25 µF and feature different terminations: the B58031I9254M062 type with L-style termination has dimensions of 10.84 mm x 7.85 mm x 4 mm, while the B58031U9254M062 with J-style termination measures only 7.14 mm […]
