HV833MG-G More Semiconductors - ICs by Microchip Technology

High Voltage, EL Lamp Driver


HV833 is a high voltage driver designed for driving EL lamps of up to 35nF (10-12in2). The input supply voltage range is from 1.8 to 6.5V. The device uses a single inductor and a minimum number of passive components. The nominal regulated output voltage that is applied to the EL lamp is ±90V. The chip can be enabled/disabled by connecting a resistor between the RSW-Osc pin and the VDD/GND pins. The HV833 has two internal oscillators, a switching MOSFET, and a high voltage EL lamp driver. The frequency for the switching MOSFET is set by an external resistor connected between the RSW-Osc pin and the VDD supply pin. The EL lamp driver frequency is set by an external resistor connected between the REL-Osc pin and the VDD pin. An external inductor is connected between the LX pin and VDD or VIN pin. A 0.003-0.1µF capacitor is connected between the CS pin and the GND pin. The EL lamp is connected between the VA pin and the VB pin. The switching MOSFET charges the external inductor and discharges it into the capacitor at CS. The voltage at CS will start to increase. Once the voltage at CS reaches a nominal value of 90V, the switching MOSFET is turned OFF to conserve power. The outputs VA and VB are configured as an H bridge and are switching in opposite states to achieve 180V peak-to-peak across the EL lamp.
