5V至3.3V輸出同步降壓型電源控制器

MAX767是一款高效、同步降壓控制器IC，專用于將5V固定電源轉(zhuǎn)換為嚴格調(diào)節(jié)的3.3V輸出。有兩個關鍵特性將該器件與類似的低壓降壓型開關穩(wěn)壓器相區(qū)別：高工作頻率和應用電路中的全N溝道結(jié)構(gòu)。300kHz的工作頻率使得外部表面貼裝元件體積非常小且成本低。\n\n 3.3μH電感用于5A電流，其物理尺寸至少比競爭解決方案中的電感小五倍。全N通道結(jié)構(gòu)和同步整流可降低成本并提高效率。在寬負載范圍內(nèi)效率超過90%，無需散熱。輸出電容要求較低，從而節(jié)省了電路板空間和成本。\n\n MAX767是一款單片BiCMOS IC，采用20引腳SSOP封裝。對于其他固定輸出電壓和封裝選項 ? 效率：>90%\n\n? 靜態(tài)電源電流：700μA\n\n? 待機電源電流：120μA\n\n? 輸入范圍：4.5V至5.5V\n\n? 低成本應用電路\n\n? 所有N通道開關\n\n? 小型外部元件\n\n? 緊縮小型封裝(SSOP)\n\n? 預先設計的應用：\n? 標準5V至3.3V DC-DC轉(zhuǎn)換器，電流高達10A\n\n? 高精度Pentium P54C VR規(guī)格電源\n\n\n\n\n? 可用的固定輸出電壓：\n? 3.3V（標準）\n\n? 3.45V（高速Pentium?）\n\n? 3.6V (PowerPC?);
