IC697HSC700
電源控制
電源設計上采用3片高效率、低壓差的線性穩(wěn)壓電源（LDO）分時工作來實現(xiàn)系統(tǒng)電源的高效管理。其中，監(jiān)控主系統(tǒng)和GPS各采用一片TPS77533供電，把航標燈電池上6.4V的電壓降到監(jiān)控系統(tǒng)所需要的3.3V電壓。TPS77533是美國TI公司生產(chǎn)的一款高效率、低壓差線性穩(wěn)壓集成電路，具有外圍電路簡單、電壓轉(zhuǎn)換效率高（最高可達92%）、輸入電壓范圍寬、使用穩(wěn)定可靠等特點，適用于絕大多數(shù)工作電壓范圍的航標燈的使用。由于通信模塊在 GPRS發(fā)射時的瞬間電流可高達2A/3.8V，因此，為了提高系統(tǒng)的穩(wěn)定性，防止各模塊之間的影響和干擾，本系統(tǒng)采用一片大功率的線性穩(wěn)壓電源 NCP630對GPRS模塊單獨供電，配合大電容蓄能濾波電路（多個電容并聯(lián)實現(xiàn)）方式，給GPRS提供充足的能量。NCP630是安森美公司的一款大電流、高效率、低壓差線性穩(wěn)壓集成電路，其最大輸出電流可達3A，最高電壓轉(zhuǎn)換效率90%，配合多個大電容的并聯(lián)，可以給GPRS模塊提供充足的能量，保證在GPRS的發(fā)射瞬間不會因電流過大而拉低模塊電壓，導致GPRS工作不穩(wěn)定。電源控制電路的結構圖如圖3所示。
