Inductor Based Dual Lamp EL Driver

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 ? Drives two EL panels, up to 4in2 each at full brightness\n? Independent input control for each of the two panels and allows PWM dimming.\n? 220VPP?regulated AC output waveform\n? 2.3V to 5.8V DC input voltage\n? Wave-shaping circuit to reduce audible noise\n? Adjustable slew rate for audible noise;
