MAX1968/MAX1969是高度集成、高性價比、高效率的的開關型驅動器，適用于Peltier熱電制冷器(TEC)模塊。兩種器件都采用直接的電流控制，消除了TEC中的浪涌電流。片內FET在提供高效率的同時，盡可能地減少了外部元件。500kHz/1MHz開關頻率和獨特的紋波消除電路減小了元件的尺寸和電源噪聲。\n\n MAX1968工作于單電源，通過在兩個同步buck穩(wěn)壓器輸出之間連接TEC，能夠提供±3A雙極性輸出。雙極性工作能夠實現(xiàn)無“死區(qū)”溫度控制，以及避免了輕載電流時的非線性問題。該方案通過少許加熱或制冷可避免控制系統(tǒng)在調整點非常接近環(huán)境工作點時的振蕩。模擬控制信號精確地設置TEC電流。MAX1969提供高達6A的單極性輸出。利用可設置限制的TEC電壓和電流，以及獨立設置限制的加熱和制冷電流，達到了最優(yōu)的可靠性。另外，還有一個模擬信號輸出，用來監(jiān)測TEC電流。\n\n MAX1968/MAX1969采用薄型28引腳TSSOP-EP封裝，工作于-40°C至+85°C的溫度范圍。焊盤裸露的增強散熱TSSOP-EP封裝，盡可能地降低了工作結溫。提供評估板，以加快設計。\n\n \n\n
