MAX8969 | 用于手持設備的升壓轉換器 MAX8969為設計簡單的1A升壓轉換器，采用小尺寸封裝，適用于所有單節(jié)鋰離子電池供電場合。IC具有保護功能，例如輸入欠壓鎖定、短路保護和熱關斷等。\n\n 輕載條件下，IC可無縫切換到跳脈沖模式，以提高效率。這種模式下，僅在需要時進行開關操作，通過降低開關頻率和電源電流來保持高效工作。\n\n 當輸入電壓接近輸出電壓時，為提高效率，提供兩種特殊的工作模式：跟蹤模式和自動跟蹤模式。這些模式允許用戶實現(xiàn)靜態(tài)電流(IQ)與進入boost模式瞬態(tài)響應時間之間的平衡。兩種模式下，p溝道MOSFET作為限流開關，VOUT保持跟蹤VIN。然而，跟蹤模式下，關閉boost電路，系統(tǒng)利用E ? 靈活的系統(tǒng)集成\n? 輸出電流高達1A\n\n? 2.5V至5.5V輸入電壓范圍\n\n? 3.3V至5.7V輸出電壓范圍\n\n\n\n\n? 集成保護提高系統(tǒng)可靠性\n? 欠壓鎖定(UVLO)\n\n? 短路保護\n\n? 過熱關斷\n\n\n\n\n? 高效率和低靜態(tài)電流延長電池壽命\n? 內置同步整流器，效率超過90%\n\n? 自動跟蹤模式下的IQ為60μA\n\n? 升壓模式下的IQ為45μA\n\n? 跟蹤模式下的IQ為30μA\n\n? 關斷電流僅為1μA\n\n? 輕載條件下的跳脈沖模式提高效率\n\n? 真關斷(True Shutdown?)防止電流從OUT_流; | ADI 亞德諾 | ADI | |
