Introduction :

德州儀器(Texas Instruments, 簡稱 TI)生產的一款非常經典且高效能的非同步降壓型 DC-DC 電源轉換晶片(Buck Converter)

核心技術規格

• 輸入電壓範圍((V_{IN})):3.5V 至 28V(非常適合 5V、12V、24V 的系統進線降壓)。
• 輸出電壓((V_{OUT})):可調式,最低可調至 0.8V(透過外部電阻分壓來設定)。
• 最大輸出電流:可連續輸出高達 3A 的電流。
• 開關頻率((F_{SW})):固定 570 kHz(在電感體積與轉換效率之間取得良好平衡)。
• 內置 MOSFET:整合了 80-mΩ 的高側(High-side)電晶體。
• 超低待機電流:關斷(Shutdown)時的靜態電流僅約 1 µA。
