AP3031 是一款基于
电感器的
DC/DC 升压转换器,设计用于驱动 LED 阵列。 1.4A 开关电流允许 AP3031 用于不同的 7' 至 10' LCD 面板背光(通常为 3-13 个 LED 阵列)。输出电流精度由反
馈电压和电阻RISET决定。为了节省空间和降低成本,AP3031正常工作在1MHz,这意味着微小的外围元件是可以接受的
说明
-
Design Consideration with AP3031 is an inductor-based DC/DC boost converter designed to drive LED arrays. 1.4A switching current allows AP3031 to be used in different 7' to 10' LCD panel backlights (3-13 LED arrays typically). The output current accuracy is determined by the feedback voltage and resistor RISET. To save space and reduce cost, this AP3031 operates at 1MHz normally, which means that the tiny periphery components are acceptable
