Intersil's New Single-Cell Boost Converters Provide Industry-Leading Power Density and Efficiency for Battery-Powered Applications

ISL9113 Delivers Up to 95% Efficiency to Maximize Battery Life

MILPITAS, CA -- (Marketwire) -- 01/09/13 -- Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high-performance analog, mixed signal and power management semiconductors, today introduced a family of boost converters delivering exceptional power density and efficiency. These new boost converters are ideal for single-cell Li-Ion powered products incorporating USB 'on-the-go' (OTG) capability.

Available with either a 5V fixed output voltage or an adjustable output, the ISL9113 is a fully-integrated synchronous boost converter that delivers an industry-leading current density of 460mA/mm2. Integrated 1.3A rated synchronous MOSFETs can deliver 5V at 500mA from a single-cell Li-ion battery. This capability is often required to power external peripherals attached to a smartphone's or tablet's USB port.

ISL9113 Features

  • 1.8MHz switching frequency permits use of tiny, low-profile inductor and capacitors
  • Low resistance MOSFETs deliver up to 95% efficiency to maximize battery life
  • 20uA quiescent current delivers excellent efficiency under light load conditions
  • Available in a tiny 0.8mm x 1.36mm WLCSP package or 2mm x 2mm DFN package

ISL9111 and ISL9111A
ISL9113 follows Intersil's popular low input voltage, synchronous boost converters; ISL9111 and ISL9111A. Their integrated 1A rated synchronous MOSFETs can deliver 100mA from a single-cell alkaline battery. The ISL9111 and ISL9111A address both rechargeable and non-rechargeable battery applications. The ISL9111 includes an under-voltage lockout (UVLO) feature, internally disabling the converter below 0.7V input voltage to prevent over-discharging an attached battery. The ISL9111A has this feature disabled to maximize the usable life of a non-rechargeable single-cell battery.

Pricing and Availability
The ISL9113 is available now in a compact 2mm x 2mm 8-lead DFN package and a 0.8mm x 1.36mm 6-bump WLSCP. Pricing starts at $1.39 each in 6,000-piece quantities. The ISL9111 and ISL9111A are available in a 6-lead SOT-23 package with prices starting at $1.20 each in 3,000-piece quantities.

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
