RT4832 是一款整合式总电源解决方案，整合闪光灯 LED 驱动器（Flash LED Driver）、背光 WLED 驱动器（Backlight WLED Driver）及 DSV 驱动器。闪光灯 LED 驱动器支援最多 2 通道、每通道最高 1.5A 的应用。背光 WLED 驱动器可提供最高 36V 输出，支援最多 10 颗 WLED 串接应用，并提供 1024 级 LED 电流调整，支援对数曲线（Logarithmic）及线性曲线（Linear）调光模式。 DSV 采用单电感升压转换器搭配反相电荷帮浦架构，相较于双电感方案可大幅减少电路板面积。负电压输出（CPOUT）由升压输出（LCMOUT）产生；同时提供 DSV 正电压输出（POS），其电源杂讯透过 LDO 进一步降低。正负输出电压皆可分别于 ±4V 至 ±6V 范围内以 50mV 为步进进行程式设定。 Flash 升压转换器可工作于 2MHz 或 4MHz 开关频率，其中 4MHz 模式可使用更小型、低高度的外部元件。Torch 模式电流可设定于 25mA 至 375mA 范围内，每级调整 25mA；Strobe 模式电流则可设定于 100mA 至 1.5A 范围内，每级调整 100mA。 DSV 可驱动最高 10 吋 TFT-LCD 面板，涵盖由小尺寸（SFF）至中尺寸（MFF，例如平板电脑）的显示器应用。正负输出电压轨通常连接至 Source Driver IC。输入电压范围为 2.5V 至 5.5V，适合单节锂离子电池、镍锂电池及锂聚合物电池应用，对称输出电流最高可达 80mA。 RT4832 内建完整保护功能，包括输入欠压锁定保护（UVLO）、输入电压监控保护、过电流保护（OCP）、过电压保护（OVP）、LED 短路保护、输出短路保护以及过温保护（OTP）。 RT4832 采用 WL-CSP-30B（2.24mm × 2.64mm，BSC）封装。
