Among the new HMI-related products making their way to market this month are two white LED drivers, a six-in-one visual display/performance management tool, a 31-in. surface-wave touchscreen, and a compact-size mulitifunctional keyboard. Details and links to more information follow. Two white LED drivers from Vishay Intertechnology are said to deliver efficiency of up to 90% during operation in compact handheld and battery-operated electronics. SiP12401 boost controller and SiP12501 boost converter are reportedly optimized to provide efficient, controlled brightness in applications including white LED backlighting for LCDs in portable electronic devices, including cell phones and digital cameras.

The SiP12401 boost controller integrated circuit (IC) uses double-cell HiMH or alkaline and LI-ion batteries to drive white LEDs connected in series for uniformly bright backlighting without the need for ballast resistors. It supports input voltage range of 1.8-5.0 V. Designed to drive white LEDs connected in parallel, the SiP12501 is a boost converter IC for single- or double-cell NiMH or alkaline battery packs. An internal low-threshold power MOSFET (metal-oxide-semiconductor field-effect transistor) lets the device start up with a low-battery voltage of 0.65 V. The two LED drivers come in lead-free 6-pin PowerPak MLP33 packages and are rated for operation over–40 to 85 °Celsius.
