Quad-Output Driver Generates 300 V

Tue, 07/14/2009 - 11:59am

ec99od601a-webUtilizing an inductor-based boost converter, a ±15kV quad-output driver (the MAX14521E) from Maxim IC generates 300Vp-p (max) voltage. A full-bridge output converts this voltage to the AC waveform required to drive an EL lamp. Intended for multiple electroluminescent (EL) lamps, the driver is ESD-protected and features an I2C interface. The driver features a proprietary acoustic-noise-reduction circuit that controls the output waveform to reproduce sine waves. Specified over the -40 degrees Celsius to 85 degrees Celsius extended temperature range, the driver is available in a 4-mm x 4-mm, 24-pin TQFN package. From $1.50 in minimum quantities of 1,000.
