RT9292 是用於 WLED 驅動的高頻、非同步 Boost 轉換器，集成了可驅動多達6只串聯 WLED 的、耐壓為 28V 的 MOSFET，適用於液晶顯示幕的背光驅動和 OLED 的供電應用。集成了軟啟動功能的 RT9292 在使用中不會出現電流衝擊，其 1MHz 的工作頻率容許使用小型的外部元件與其配合工作，同時具有很好的 EMI 性能。對於低壓應用場合，它提供了26V的過壓保護點以支援使用低成本的小型輸出電容。提供給 LED 的電流大小是由外部電流檢測電阻 R<sub>SET</sub> 所確定的，其回饋電壓大小有兩種參數： 104mV 和 330mV 。RT9292 的可選封裝是 TSOT-23-6 和 WDFN-8L 2x2，可為不同的 PCB 設計和最佳的成本結構提供最好的選擇。
