摘　　要：DQC-I智能流速仪是便携式仪器中的一种,它具有便携式仪器的特点。要求电源必须是体积小巧,并具有相当容量的直流电源,由于受巡回检测环境条件的限制,只能选用电池供电,因此,尽量降低仪器的功耗,延长电池使用寿命成了仪器研制中的首要问题。为了解决这一问题最终选择MAX757电源转换芯片,实验数据表明使用MAX757进行电源转换效果很好,达到了预期目的。The DQC-I intelligent velocity instrument is a kind of portable instruments, it＇s characteristic which power volume is small and high capacity of portable instruments. Due to restrict of circuit measure environment,choose battery, Chief problem of manufacture instrument is which reduce loss and prolong maketime of battery resolved by MAX757 of power conversion chip. The experiment datas show that the MAX757 is very good chip of conversion power desired expect purpose.
