HV845 - Low Noise Dual EL Lamp Driver

Description

The Supertex HV845 is a low noise, high voltage driver designed for driving two EL lamps with a combined area of 3.5 square inches.

The input supply voltage range is from 2.0V to 5.8V.

The device is designed to reduce the amount of audible noise emitted by the lamp.

Features

  • Low audible noise.
  • Independent input control for lamp selection.
  • 180VPP output voltage.
  • Split supply capability.
  • Patented output timing.
  • One miniature inductor to power both lamps.
  • Low shutdown current.
  • Wide input voltage range 2.0V to 5.8V.
  • Output voltage regulation.
  • No SCR output.
  • Available in 12-Lead QFN/MLP package.
