The HV857L is a low noise, high voltage driver?designed for driving Electroluminescent (EL) lamps of up to five?square inches. It is the low noise version of the EL lamp driver?HV857. The input supply voltage range is from 1.8V to 5.0V. 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 ±95V. The chip can be enabled/disabled by?connecting the resistor on RSW-Osc to VDD/ground.?The HV857L 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 supply pin, VDD. The EL?lamp driver frequency is set by an external resistor connected?between the REL-Osc and VDD pins. An external inductor is?connected between the LX and VDD pins, or VIN for split supply?applications. A 0.003-0.1μF capacitor is connected between CS?and ground. The EL lamp is connected between the VA and VB?pins.?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 95V, 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 ±95V across the?EL lamp. 类似型号HV853K7-G, HV853MG-G, HV857K7-G, HV857LMG-G, MIC4830YML-TR, MIC4830YMM, MIC4830YMM-TR
