MIC4833 的典型应用是背光应用中使用的低噪声双
电致发光 (EL) 面板驱动器。 MIC4833 使用升压转换器将低
直流电压转换为高直流电压,然后使用 H 桥在 EL 面板上交替高直流电压。 MIC4833 包含专门设计用于减少 EL 面板发出的可听噪声的内部波形整形电路。可以通过向设备施加 PWM 信号来调暗两个 EL 面板。 MIC4833 通过单个
电感器驱动两个输出,并且需要最少数量的无源组件
说明
-
Typical Application for the MIC4833 is a low noise dual electroluminescent (EL) panel driver used in backlighting applications. The MIC4833 converts a low DC voltage to a high DC voltage using a boost converter and then alternates the high DC voltage across the EL panels using an H-bridge. The MIC4833 incorporates internal wave-shaping circuitry specifically designed to reduce audible noise emitted by EL panels. The two EL panels may be dimmed by applying a PWM signal to the device. The MIC4833 drives two outputs from a single inductor and requires a minimum number of passive components
