October 15, 2008 San Jose, California / Account Manager / - provides integrated circuit solutions for the world's leading manufacturer, today launched the product Micrel MIC4833 / 4, this is a new low noise electroluminescent lamp 220Vpp (EL) driver petite refined products, were used to drive two area of 4 square inches of panels. The product can be used in mobile phones, personal media players, portable navigation devices and remote control backlight applications, but can also used for automotive and industrial equipment, general lighting applications.
For portable products, Micrel's marketing director, Andy Khayat business that, MIC4833 / 4 product significantly reduces the need to use more than one EL lamp and the limited size of the scale of application solutions. The product only uses a single inductor and a minimum limit of external passive components, can drive two EL lamps, making the total volume of the solution from the point of view, is very sensitive to the size and cost of battery-powered ideal solution for portable products.
MIC4833 and MIC4834 only 152 microamps of current can be part of the realization of high performance. Both products use integrated circuits, Micrel's advanced Bipolar-CMOS-DMOS (BCD) technology, integrated high-voltage boost converter and a large EL lamp drive new H bridge driver. Previous design often produce annoying hum, compared with the new H-bridge design throughout the EL lamp panel to generate a more stable AC waveform, eliminating the annoying noise may be audible. MIC4833 / 4 of the working voltage 2.3-5.8V, suitable for a lithium battery, 2 or 3 alkaline batteries / Ni-Cd battery / Ni-MH battery-powered applications. Each EL lamp driver are independent enable and stop, EL lamp brightness adjustment by changing the device within the EL lamp oscillator frequency to achieve. MIC4833 also has control of EL light output conversion functions, to further reduce audible noise. MIC4833 RoHS compliance with the standard 12-pin 3mm x 3mm MLF? Forms of packaging. MIC4834 uses a 10-pin 3mm x 3mm MLF? And 10-pin MSOP package form. Product application temperature range -40 to 125 degrees Celsius.
