HV862 Dimmable, Low Noise, Dual EL Lamp Driver Features ► Adjustable output regulation for dimming ► Lamp fade-in/fade-out capability ► Low audible noise ► 180VPP output voltage for higher brightness ► 1.5V enable input logic high ► Single cell lithium ion compatible ► One miniature inductor to power both lamps ► Separately adjustable lamp and converter frequencies ► Split supply capability ► 16-Lead QFN package Applications ► Dual display cellular phones ► Keypad and LCD backlighting ► PDAs ► Handheld wireless communication products ► Global Positioning Systems (GPS) The device uses a single inductor and a minimum number of passive components. Using the internal reference voltage, the regulated output voltage is at a nominal value of 90V. The EL Lamps will therefore see ±90V.
