Electroluminescent Lamp

Driver IC

The MC33441 is a DC–AC inverter integrated circuit for driving EL lamps.

It can boost the supply voltage to the level required by EL lamps and also

provide high voltage AC lamp excitation. It consists of an oscillator, a

frequency divider, a coil driving circuit and a switched H–bridge network. The

input supply voltage range is from 1.8V to 3.5V and is capable to supply a

typical 140Vpp AC output voltage. The standby current of the device is

typically 10nA which is ideal for low power portable products. Externally, one

inductor and one resistor are needed to generate the desirable voltage

charge and to fine tune the oscillator’s frequency. This device is offered in

8–Pin TSSOP miniature package. The operating temperature is –20°C to

70°C.

Features:

• Battery Operation 1.8V – 3.5V

• Typical Voltage Output 140Vpp

• Typical Standby Current 10nA

• Internal Oscillator with External Tuning Resistor

• Enable Control Pin with a 300K Internal Pull–Down Resistor

• 8–Pin TSSOP Package (Thickness = 1.05mm, Width = 4.5mm,

Length = 3.1mm & Lead Pitch = 0.65mm)

Types of Applications:

• Pagers, Cellular Phones, Portable CD Players/Minidisks

• Databanks, Calculators
