The LMR16006Y-Q1 is a PWM DC-DC buck (step-down) regulator. It is suitable for a wide range of application from industrial to automotive for power conditioning from an unregulated source. The regulator’s standby current is 28 µA in ECO mode, which is suitable for battery operating systems. An ultra-low 1 µA shutdown current can further prolong battery life. Operating frequency is fixed at 2.1 MHz allowing the use of small external components while still being able to have low output ripple voltage. Soft-start and compensation circuits are implemented internally, which allows the device to be used with minimized external components. The LMR16006Y-Q1 is optimized for up to 600 mA load currents. It has a 0.765 V typical feedback voltage. The device has built-in protection features such as pulse by pulse current limit, thermal sensing and shutdown due to excessive power dissipation. The LMR16006Y-Q1 is available in a low profile SOT-6L package (2.9 mm × 1.6 mm).

PMP10710 — 運用同級最佳升壓控制器的公開音訊參考設計

PMP10710 是一款用於公共廣播音訊系統的 200W 設計，可用於 100W + 100W 立體聲或 200W 低音揚聲器應用。本設計大致分為四個主要階段：

  1. 採用 LM5122 控制器 IC 的單相同步升壓轉換器。  此設計接受 10V 至 15VIN 的輸入電壓（額定 12VIN），並提供 30V 的輸出，可為負載提供 6.5A 連續電流。
  2. 使用 TAS5611 D 類裝置的 100W + 100W 立體聲音訊放大器。
  3. 立體聲輸入使用 OPA1632 差動放大器的單端至差動轉換（具主動低通濾波器）。
  4. Simple Switcher LM16006 用於滿足所有輔助電源需求。
