White LED Step-Up Converter

IXYS Features: • • • • 1.1V to 5.5V Input Range 2 Amp Peak Switch Current High Efficiency > 80% 20V Maximum Output with Over-Voltage Protection • LED Intensity Control • 1.0 MHz Fixed Frequency Switching • 8 Lead SOIC Package MX841 White LED Step-Up Converter General Description The MX841 is a fixed frequency, constant current source step-up DC/DC converter. The output current is directly regulated making the MX841 ideal for driving series connected white light emitting diodes (LED’s) in backlight applications. The MX841 powers up to 3 series white LED’s at 1.1V, and 20 series/parallel white LED’s at 5.0V. The MX841 features a 1.0MHz switching frequency to accommodate the use of small capacitors and a small inductor necessary in size sensitive portable applications. Light intensity and shutdown are conveniently controlled by a single analog voltage. Power efficiency and battery life are extended through the use of a high voltage, low RDSON Nchannel MOSFET switch. The MX841 is designed to operate over a temperature range of -40°C to +85°C, and is available in an SOIC-8 Package, with or without an Exposed Pad in Tube or on Tape and Reel. (Alternate package types available upon request). Applications: • White LED Display Backlighting - Low Voltage: Mobile Phones, PDA’s, MP3 Players, Digital Cameras - High Drive Current: Vehicle Instrumentation Panels Ordering Information Part No. 17000-00TU 17000-00TR 17043-00TU 17043-00TR Description SOIC-8 Standard Tube SOIC-8 Standard T&R.
