Reflector diffuser technology boosts backlights
A new series of backlight panels is available in a variety of colours and sizes, making them ideal for a wide range of applications.
High-flux LEDs boast enhanced thermal performance
New from Marktech Optoelectronics is the Dorado series of high flux LEDs.
Toshiba has engineered the TB62750FTG step-up DC/DC convertor white LED driver to provide an ideal combination of over-voltage protection, high-precision current regulation and high power-efficiency for today's advanced portable devices.
The optimised design minimises the total circuit sise which can contribute to an applications small footprint.
The TB62750FTG can be operated in "light mode" which allows continuous operation of up to 350mA or in "flash mode" with a constant current of 800mA maximum and 300ms maximum light time.
The high power-efficiency of 80% extends rechargeable battery life.
The device achieves high-precision current regulation of +/-2% of the required value; this allows exact control of backlight brightness and uniformity.
Solid state high intensity LED lighting is increasing in popularity for cameras requiring flash and strobe effects.
In addition, colour LED panels are continuing to gain popularity in handheld electronics, test equipment and instrumentation.
Because these devices run on battery power with finite battery life, it is becoming more common to use a white LED that can emit bright light for backlighting while consuming little power.
As a result, world demand for white LEDs is rapidly increasing.
Toshiba and Marktech are meeting these needs by bringing to market a white LED driver that realises low-power consumption, high efficiency and high precision.
Pricing for the TB62750FTG is $1.65 in 1000-unit lots with free samples currently available.
