Diodes, Inc. Announces High Efficiency Charge Pump White LED Driver for Portable Electronic Devices
Phones, PDAs, Smart Phones and MP3/MP4 Players Business Editors/High-Tech Writers DALLAS--(BUSINESS WIRE)--Oct. 2, 2007--Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, today announced the release of the AP3152, Diodes' first high efficiency charge pump white LED (WLED) driver for small-sized LCD display panels found in cellular phones, PDAs, smart phones, MP3/MP4 players and many other portable electronic devices.
The AP3152 features a patent pending Serial Digital Interface (SDI) that offers designers three modes of operation to manage each LED channel's brightness with incomparable flexibility and accuracy. With the SDI control, the internal switching frequency of the AP3152 can be set to 1.2MHz, 0.6MHz or 1.8MHz to maximize efficiency and to match outputs of LED system requirements in portable devices. The AP3152 drives up to four channels of white LEDs and can control the brightness intensity of each channel. This product is ideal for a broad range of small LCD backlighting display applications that require two, three, or four white LEDs with high-precision current matching, such as cell phones and PDAs.
"The AP3152's unique SDI control feature and ultra-thin DFN package provides Diodes a significant advantage in the small compact LCD market," said Mark King, Senior VP of Sales and Marketing of Diodes, Inc. "This product is the first of a new series that will address the portable display market, which complements our existing analog power, hall sensors and discrete product solutions and expands our opportunity to capture increased share in this growing market."
The AP3152 has an ultra-thin DFN package with a maximum height of 0.6mm that makes it suitable for integration into thin and compact LCD display panels where space and height are at a premium. The AP3152 includes additional features such as Soft Start for start-up or mode switching, Spread Spectrum Control that can significantly reduce the effects of EMI to the system, short circuit protection, over voltage protection, and under voltage lockout. The AP3152 is available in a 12-pin DFN3030-12 package and is fully RoHS compliant, including Green Molding compound. The AP3152 supports an industrial temperature range of -40 degrees C to +85 degrees C.
