【经验】拓尔微电子降压DCDC芯片TMI3343的外围电路设计经验
TMI3343是一个宽压同步高效率的降压DCDC芯片,最大输出电流可达3A并且软启动事件可调,它集成了低导通电阻的开关:120mΩ的高侧开关与80mΩ的低侧功率MOS。关断电流低于3μA,固定340KHz的开关频率,另外还具有很多先进功能,可使用在机器人、打印机、总线等应用场合上。本文主要介绍了拓尔微电子的降压DCDC芯片TMI3343在设计中的一些外围电路设计的经验,给大家在设计中一些参考。以下为芯片的引脚示意图:
BS引脚为高侧门驱动引脚,一般在BS引脚与SW间通过一个100nf的电容连接,此电容为自举电容,内部的高端MOS需要得到比IC的VCC更高的电压,通过自举电容即可得到,否则高端MOS无法驱动。
SW是开关引脚,连接至外部的电感器,电感器的感量与电流可通过规格书中的公式计算。
EN引脚为使能引脚,VEN大于1.5V时设备开启,低于0.4V时设备关闭,注意此脚不要悬空。如果不需要用逻辑信号控制此脚可通过电阻上拉至CC,但是要注意电阻的阻值,此脚的输入电流不要超过1mA。
FB引脚为电压反馈引脚,可通过输出电压下拉两个电阻通过分压输入给FB,FB引脚内部含有一个0.8V的基准源,通过比较器改变占空比从而稳定想要的输出电压,在电阻上可并联一个电容使得环路更稳定,如图所示:
SS引脚为缓启动时间设置引脚,时间Tss可参考规格书中的计算公式计算得到。
希望以上经验对大家设计有所帮助。

【应用】集成电感的降压DCDC芯片IM6001助力车载DCDC设计,5V转3.3V效率高达93%
车载DCDC产品辅助电源中主控芯片供电一般采用5V转3.3V,之前不少设计会采用线性稳压器或低压DCDC设计,但以上两种方案分别存在效率低和布板面积过大问题,本文推荐拓尔微集成电感同步降压芯片IM6001。
