IC697LBR701
電源控制
電源設(shè)計(jì)上采用3片高效率、低壓差的線性穩(wěn)壓電源（LDO）分時(shí)工作來實(shí)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(biāo)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(guó)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(jiǎn)單、電壓轉(zhuǎn)換效率高（最高可達(dá)92%）、輸入電壓范圍寬、使用穩(wěn)定可靠等特點(diǎn)，適用于絕大多數(shù)工作電壓范圍的航標(biāo)燈的使用。由于通信模塊在 GPRS發(fā)射時(shí)的瞬間電流可高達(dá)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(duì)GPRS模塊單獨(dú)供電，配合大電容蓄能濾波電路（多個(gè)電容并聯(lián)實(shí)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(dá)3A，最高電壓轉(zhuǎn)換效率90%，配合多個(gè)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(huì)因電流過大而拉低模塊電壓，導(dǎo)致GPRS工作不穩(wěn)定。電源控制電路的結(jié)構(gòu)圖如圖3所示。
