MIC4833  
Low Noise Dual 220 VPP EL Driver  
With Output Voltage Slew Rate Control  
General Description  
Features  
•
Drives two EL panels, up to 4 in2 each at full  
brightness  
The MIC4833 is a low noise dual Electroluminescent (EL)  
Panel driver used in backlighting applications. The  
MIC4833 converts a low DC voltage to a high DC voltage  
using a boost converter and then alternates the high DC  
voltage across the EL panels using an H-bridge. The  
MIC4833 incorporates internal wave-shaping circuitry  
specifically designed to reduce audible noise emitted by  
EL panels. The two EL panels may be dimmed by applying  
a PWM signal to the device. The MIC4833 drives two  
outputs from a single inductor and requires a minimum  
number of passive components. It features an operating  
input voltage range of 2.3V to 5.8V, making it suitable for  
1-cell Li-ion and 2- or 3-cell alkaline/NiCad/NiMH battery  
applications.  
•
Independent input control for each of the two panels  
and allows PWM dimming.

220Vpp regulated AC output waveform  
2.3V to 5.8V DC input voltage  
Wave-shaping circuit to reduce audible noise  
Adjustable slew rate for audible noise reduction  
Independently adjustable boost converter and EL  
panel frequency

•
Single inductor to power both panels  
0.1uA typical shutdown current  
12 pin 3mmx3mm MLF® package  
–40oC to +125oC junction temperature range  
An external resistor may be used to adjust the output  
voltage slew rate to reduce audible noise. The MIC4833  
features separate oscillators for the boost and H-bridge  
stages to allow independent control. External resistors set  
the operating frequencies of each stage allowing the EL  
circuit to optimize efficiency and brightness.

The MIC4833 is available in a 12 pin 3mmx3mm MLF®  
package, and has an operating junction temperature range  
of –40°C to +125°C.
