· We show how to build a driver for a high-voltage electroluminescent backlight using an inductor, microcontroller, and a handful of other www.doorway.ru more. An electronic device () is disclosed including an electroluminescent (EL) backlight panel () and an EL driver circuit (). The EL driver circuit () provides power to the EL backlight (), as well as panel aging compensation and user adjustment capabilities. The EL driver circuit () is low-cost, small-size, and designed in such a way to be easily integrated into a custom integrated www.doorway.ru by: © IMP, Inc. Electroluminescent Lamp Driver v The IMP Electroluminescent (EL) lamp driver is designed for systems that must operate down to 1V and below. The input sup-ply voltage range is V to V. Typical output lamp drive volt-age is V peak-to-peak. EL lamps of up to 6nF capacitance can be driven to high brightness.

Meaning, would using a different circuit or with "better" components alleviate the high pitched whine of the cheaper supplies. The 12v little cube I have (from Chinese ebay seller) appears already expoxied/sealed but still noisy (I'm running 12v LED strips as well as EL, thus needing the 12v version). EL Wire is a-bit strange in that it requires high voltage AC at a high frequency to work. Also its acts like a capacitor, FYI. It needs to be driven at about 60 Volts Hz (although it may work with a lower frequency, it will be dimmer). (Current draw mA) Also just the keep things interesting, I intend to drive it from a single V battery.
Zsp Electroluminescent Lamp Driver,application circuits. 18 มิ.ย. An AC source is essential to power EL wire and it must be a sine wave with zero DC component. A simple EL Wire inverter can drive up to Depending on your setup, you will need to understand how a circuit works. The battery pack included in the EL starter kit and the chasing inverter are.
