Intersil has unveiled PowerNavigator version 5.2 with added features, a free, downloadable GUI that helps system designers quickly configure, validate, monitor and optimise their power supply architectures. Combined with the drag-and-drop GUI interface, PowerNavigator 5.2 makes it straightforward to change features and functions of a digital power supply design without writing a single line of code.
PMICs enable credit-card-sized tablet motherboards
Intersil has introduced a pair of integrated PMICs that enable the industry’s first credit card-size motherboards for high-end ultrabook and tablet computers powered by 2-cell Li-ion batteries. The single-chip ISL95908 PMIC delivers eight voltage rails optimised to support subsystem peripheral power requirements for Intel IMVP8 platforms, and the single-chip ISL95906 provides eight power rails for VR12.6-compliant systems.
Battery management system tutorial
Today’s electronic devices have higher mobility and are greener than ever before. Battery advancements are fueling this progression in a wide range of products from portable power tools to PHEVs and wireless speakers. In recent years, the efficiency of a battery in terms of how much power it can output with respect to size and weight has dramatically improved.
What goes around
The demand for more sophisticated electronic industrial motor control is growing. Steve Rogerson looks at the drivers and the difficulties facing developers.
50A encapsulated digital power module is 'industry's first'
A 50A, fully encapsulated digital DC/DC PMBus power module, claimed to be the industry’s first, has been released by Intersil. The ISL8272M is a complete step-down power supply that delivers up to 50A of output current from industry standard 12V or 5V input power rails, and four modules can be combined to support up to 200A rails.
Increase system reliability for POL conversions
Delivering up to 2A of continuous output current from a 2.7-5.5V input supply, the ISL8002B synchronous buck (step-down) switching regulator has been introduced by Intersil. The device’s 2MHz switching frequency provides superior transient response, while its programmable soft-start, and output tracking and sequencing of FPGAs and MPUs increase system reliability for POL conversions in networking, factory automation, instrumentation an...
Analogue video decoder generates 360° surround image
Designed to improve safety for drivers and pedestrians, a four-channel analogue video decoder with a built-in analogue video encoder, has been released by Intersil. The TW9984, which replaces up to nine discrete components with a single chip, generates 360° surround images for ADAS.
Intersil ICs used in NASA's Orion spacecraft
16 of Intersil's radiation-hardened ICs were on board the maiden voyage of NASA's Orion spacecraft, also known as the uncrewed Exploration Flight Test 1, on 5th December 2014. The Orion spacecraft is designed to go where no man has gone before, exploring and collecting asteroid samples, a future planned robotic mission to redirect an asteroid to orbit the moon, and the long sought after manned mission to Mars.
Module simplifies power supply design for FPGAs
A dual 3A/single 6A step-down DC/DC power module, which simplifies power supply design for FPGAs, ASICs, MPUs and DSPs, has been introduced by Intersil. The ISL8203M measures 9.0x6.5x1.83mm and features an efficiency of 95%, providing power system designers with a high performance, easy to use solution for their low power, low voltage applications.
