Industrial DC/DC Buck Converters
To achieve the most efficient regulator design,
several factors must be considered with respect to
power management architecture and technology.
Understanding application requirements such as
output regulation, operating voltage, temperature
range, transient response, system footprint, and
component budget are important evaluation points
that should be taken in the initial design steps.
Low Power Microcontroller (Lapis)
In today’s energy consumption and safety-conscious
world, collecting and using accurate information about
ambient temperature and humidity and the concentration
of carbon monoxide (CO) is of critical importance. It
is equally important to make measurements and provide
control information or actions in a cost-effective manner.
According to the Semiconductor Industry Association,
consumer electronics became the largest user and
primary driver of semiconductors in 2004 and continues
to increase over the corporate market segment. In
consumer electronics, portable products are the fastest
H-Bridge Driver ICs
DC brush motors are increasingly required for a broad range of applications including robotics, portable electronics, sporting equipment, appliances, medical devices, automotive applications, power tools and many others. The motor itself is a preferred alternative because it is simple, reliable and low cost.
Current Mode Step-Down Regulators
Efficiency ratings for power supplies at full load do not adequately reflect the unit’s power consumption under actual operation conditions. To extend the length of operation of portable products on a single battery charge, power must be reduced in all operating modes.
Ambient Light Sensor ICs
In portable electronic products, reducing the power consumption to provide the user with increased battery life is one of today’s critical design considerations. The liquid crystal display (LCD) and its associated backlighting are among the more (and frequently the most) power hungry loads in portable products.
CMOS LDO Regulators
Power management has become an increasingly
important design consideration for numerous products,
especially those relying on battery power. Complicating
the power management situation, as more features get
integrated into products, the number of required voltage
Stepper Motor Drivers
By rotating in discrete angular increments, stepping,
stepper or simply step motors provide a more precise
solution for many motion control and measurement
applications, especially when the appropriate driver
technology is used.
The usage of lighting-emitting diodes (LEDs) in automotive applications is increasing for many of the same reasons that LED lighting is penetrating non-automotive sectors. LEDs are more efficient and smaller in size, have a substantially longer life, allow considerably greater design freedom for improved esthetics, and more.
Silicon Carbide - Schottky Barrier Diodes
The semiconductor industry has a well-established history of “smaller, faster, and cheaper.” Improving performance and reducing device cost while shrinking packaging size is fundamental to virtually every semiconductor product type.
OIS - Optical Image Stabilization
Whether capturing still images or recording
moving video, image stabilization will always
be a major factor in reproducing a near perfect
digital replica. A lack thereof will result in image
distortion through pixel blurring and the creation
of unwanted artifacts.
SiC - MOSFETs
The world has benefitted from technology
innovations and continued advancements that
have contributed to highly integrated and robust
power systems. But all this power can have a
downside in the form of higher energy costs
and the negative environmental side effects
of producing and consuming an increasing
amount of energy to run these products.
KX23H-Sensor Functionality (Kionix)
Sensors play a key role in enabling modern electronics to more intelligently
act within their environment. A cell phone, for example, uses sensors to detect
when a user is holding the device to his or her ear so it can save power by turning
off the display.
KMX62G-Magnetic Gyroscopes (Kionix)
Being able to determine a device’s position and movement is becoming a standard
feature in many portable systems. Systems such as cell phones and tablets
use the 6-axis data from accelerometers and magnetometers to enable key functions
that make consumer electronics interfaces easier and more intuitive to use.
Efficient power management is an important
design element enabling systems developers to
overcome increasing demands for compact size,
low-power operation and improved functionality.
