Product details

Description

The SP4405 is a high voltage output DC-AC inverter specifically designed to drive electroluminescent lamps to backlight liquid crystal displays, keypads, and backlit readouts used in battery operated portable equipment.

Features

an internal feedback loop that regulates the lamp voltage output to 160VPP (typical) with varying supply voltages to maintain constant EL lamp brightness over the life of the battery. The device also has a low power shutdown mode which draws less than 50nA (typical), ideal for low power portable products. One external inductor is required to generate the high voltage AC output. One external resistor is used to set the internal oscillator frequency. The SP4405 is ideal for portable.
