HV852 - High-Voltage Low-Noise Inductorless EL Lamp Driver

Datasheet Summary

Description

The HV852 is a high-voltage low-noise, inductorless EL lamp driver.

It is designed to drive EL lamps of up to 1.5 in2, with capacitive values of up to 5.3 nF over an input voltage range of 2.4V to 5V.

The HV852 converts a low-voltage DC input to a high-voltage AC output across an EL lamp.

Features

  • No External Components required when using an External Electroluminescent (EL) Clock Frequency.
  • EL Frequency can be set by an External Resistor.
  • Low Noise.
  • DC to AC Converter.
  • Drives up to 5.3 nF Load (approximately 1.5 in 2 Lamp).
  • Output Voltage Regulation.
  • Enable Function.
  • EL Lamp Dimming.
