Description
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.
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
typical 170VP-P AC signal required to drive an EL
lamp.
The configuration of the CPC6826, with designer
access to important components, allows maximum
design flexibility for optimal efficiency and brightness.
