Point of Load (POL) power supplies are used extensively in handheld devices, such as tablet computers, smart phones, as well as computer and data center motherboards. In handheld devices, POL is used to convert the battery voltage (normally around 3.7V) to power the digital IC (at around 1V) and to power the LED display screen (at around 3 to 5V). Several POLs will be needed in one handheld device. In computer and data center motherboards, the POL is used to converter the DC voltage of 12V to CPU, RAM, communication port, hard driver, etc. Integrated POL can significantly reduce the board area of POL and therefore, reduce the overall size of these devices. With the exponential growth in this area, the market for integrated POL will also expand significantly.

负载点（POL）电源广泛用于手持设备，例如平板电脑、智能手机以及计算机和数据中心主板。在手持设备中，POL用于转换电池电压（通常约3.7V），为数字IC供电（约1V），并为LED显示屏供电（约3至5V）。在一个手持设备中需要多个POL。在计算机和数据中心主板中，POL用于将12V的直流电压转换为CPU，RAM，通信端口，硬盘驱动器等。集成POL可以显着减少POL的板面积，从而减少这些设备的整体尺寸。随着这一领域的指数增长，集成POL的市场也将显着扩大。
