High Voltage EL Lamp Driver

Features

Description

• 1.8V to 3.5V Supply Voltage

• DC to AC Conversion

Clare’s CPC6826 is an electroluminescent (EL) lamp

driver that is designed for applications operating with

an input supply voltage range of 1.8V to 3.5V. The

CPC6826 can also be used in a split-supply

configuration, which enables the designer to specify

operation with an input voltage as low as 1.5V.

• Adjustable Output Frequency

• Adjustable Switch Frequency

• Output Voltage Regulation

• Enable/Disable Function

• Split Power Supply Capability

• < 100nA Shutdown Current

Only five passive, external components are required:

an inductor, a capacitor, and a diode to complete the

boost switcher circuit; and two resistors to set the

frequency of the two internal oscillators. These few

components and the CPC6826 together generate the

• Pagers

• Portable Transceivers

• Remote Control Units

• Calculators

lamp.

The configuration of the CPC6826, with designer

access to important components, allows maximum

design flexibility for optimal efficiency and brightness.
