The LMR60430-Q1 is a 3V to 36V (42V transient), 3A, automotive-grade synchronous buck converter in an ultra compact 2.5mm × 2mm QFN-9 package or 3.5mm × 2.5mm QFN-11 packagewith wettable flanks. The HotRod™ QFN package with mitigated interference and noise technology using architecture 1 features (MINT 1) achieves low EMI performance to facilitate qualification of automotive and other noise-sensitive designs.

All device variants are capable of output voltages ranging from 1V to 20V in adjustable output configuration. Each variant is also capable of delivering a fixed output voltage by connecting the output voltage node directly to the feedback pin. The Device Comparison provides details on the fixed output voltage options. The current-mode control architecture with 30ns minimum on-time allows high conversion ratios at high frequencies, fast transient response, and excellent load and line regulation.

Open drain power-good output facilitates power sequencing requirements. The MODE/SYNC pin of the LMR60430-Q1 allows the user to select between forced pulse width modulation (FPWM), auto mode, or external synchronization mode of operation.

The LMR60430-Q1 is designed to offer reduced output capacitance leading to compact PCB layout and system cost savings. The LMR60430-Q1 is a part of a family of pin-compatible devices ranging in current levels from 0.6A to 6A.

參考設計

PMP31344 — 車用、12V 輸入、140W 雙埠 USB 電力傳輸，支援 DisplayPort™ ALT 模式參考設計

此參考設計為車用 USB 擴充功率範圍 (EPR) 系統，可為兩個 USB Type-C® 埠同時提供電源與數位通訊功能。連接 USB-C 纜線時，TPS26744E-Q1 會與插入式裝置協商目標輸出電壓和最大電流。接著控制器會啟用並適當驅動處理電力傳輸的降壓升壓控制器 (LM251772)。

在通訊端，TPS26744E-Q1 可與連接的 USB 裝置（例如手機或筆記型電腦）協商 USB-DP 模式的選擇。接著，顯示器強制轉型則可透過 USB 多工器 (MUX) (TUSB564-Q1)、DP MUX (TS3DV642) 及平板顯示器 (FPD)-Link 序列器啟用。
