HV830中文资料High Voltage, EL Lamp Driver IC数据手册Microchip规格书

描述 Description

HV830 is a high-voltage driver designed for driving EL lamps of up to 50nF. EL lamps greater than 50nF can be driven for applications not requiring high brightness. The input supply voltage range is from 2.0 to 9.5V. 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 ±100V. The chip can be enabled by connecting the resistors on the RSW-Osc and REL-Osc pins to the VDD pin, and disabled when connected to GND.The HV830 has two internal oscillators, a switching MOSFET and a high-voltage EL lamp driver. The frequency of the switching converter MOSFET is set by an external resistor connected between the RSW-Osc and the VDD pins. The EL lamp driver frequency is set by an external resistor connected between the REL-Osc and the VDD pins. An external inductor is connected between the LX and VDD pins. A 0.01µF to 0.1µF capacitor is connected between the CS pin and the GND. The EL lamp is connected between the VA and VB pins.The switching MOSFET charges the external inductor and discharges it into the CS capacitor. The voltage at CS will start to increase. Once the voltage at CS reaches a nominal value of 100V, the switching MOSFET is turned OFF to conserve power. The output pins VA and VB are configured as an H-bridge and are switched in opposite states to achieve 200V peak-to-peak across the EL lamp.
