HV861 is a low noise, dimmable, high voltage, dual EL Lamp driver designed for driving two electroluminescent (EL) Lamps with a combined area of 5.0 square inches. The input supply voltage range is from 2.5V to 4.5V. Enable input logic high can go as low as 1.5V, which allows logic interface operating from typical 1.8V supplies.The device is designed to minimize audible noise emitted by the EL Lamps. The device uses a single inductor and a minimum number of passive components. Using the internal reference v
