技术问答

A9910是由AIT推出的适用于通用高亮度AC-DC LED场景，是一个PWM高效LED驱动器控制芯片，它允许高亮度LED高效稳定地运行在直流10V到直流600V的电压源中。A9910控制一个固定开关频率高达300kHz的外部MOSFET。开关频率可以通过单个电阻进行调节。串联的LED以恒定电流而不是恒定电压驱动，从而提供稳定的光强输出和可靠性。输出电流可在几毫安和超过1.0A之间调节。A9910采用坚固的高压接线隔离工艺，可承受高达600V的输入电压冲击。LED串连的输出电流通过线性控制输入端施加外部控制电压，输出电流可在0到最大值之间随意调节。A9910提供一个低频PWM输入，可接受0-100%的占空比和频率高达几千赫兹的外部控制信号。

图1 典型应用原理图

A9910是一款转化效率高，输入电压阈值范围较大（最高可为600V）的LED驱动器芯片，适用于家庭或者工业电压环境。芯片工作温度范围为-45℃~85℃，最高结温125℃，TA=25℃下，功率散耗为630mW，功耗较低。在断电模式下，电流为0.5~1mA。芯片采用SOP8封装，封装尺寸如下图2所示。
