**The IMP528 is an Electroluminescent (EL) lamp driver with the four EL
lamp driving functions on-chip. These are the switch-mode power supply, its high-frequency oscillator, the high-voltage H-bridge lamp driver and its low- frequency oscillator. The IMP528 drives EL lamps of up to 50nF capacitance to high brightness; EL lamps with capacitances greater than 50nF can be driven, but will be lower in light output. The typical regulated output voltage that is applied to the EL lamp is 220V peak-to peak. The circuit requires few external components; a single inductor, single diode, two capacitors and two resistors. Two of these resistors set the frequency for two internal oscillators.**
Unlike other EL lamp drivers, the IMP528 does not require an external
protection resistor in series with the EL lamp.
The IMP528 operates over a 2.0V to 6.5V supply voltage range. A regulated,
low-power source can supply the low quiescent current of the IMP528. The
inductor may be driven from an independent, unregulated supply voltage in dual
supply applications.
An internal circuit shuts down the switching regulator when the lamp drive
voltage reaches 220V peak-to-peak. This conserves power and extends battery
life.
The IMP528 is available in MicroSO and SO-8 packages and in die or wafer form.
