您好
1, 不能同时连接EV2400和单片机,会通讯冲突。
2, 请参考TRM section 16.4 of the BQ78350-R1A. You need to set the [FIXED_ADDR] bit to zero in data flash and then use a resistor divider on the SMBA pin to set the voltage corresponding to the address you want to set.
3,请参考下面文档…
Part Number: TPS53915 Other Parts Discussed in Thread: TPS65400 你好,
请教2个问题:
1,我们评估TPS53915电源芯片,我看datasheet VOUT:0.6V-5.5V没有问题,但是看到PMbus调整输出电压范围只有+12%- -11.6%,这样比如我设置4V,那么调整范围只有3.536-4.48V,范围比较小还是我理解的有误?
2,可以帮忙推荐下类似XRP7724的替代料吗?要求12V输入,1V-5.5V通过I2C或者PMbus可调输出…
Part Number: BQ34Z100-G1 quit current设置为40ma,待机平均电流维持在30ma左右,等了一分钟左右firstdod置1了,代表成功进入了relax mode。但是等待了30多分钟,一直没有读取ocv,中间一直也没有跳出relax mode,电流相对比较稳定的 。log日志如下。 Fri Oct 25 09:56:45 CST 2024

Part Number: LM5069 Other Parts Discussed in Thread: CSD19536KTT
Hi Ti engineer,
请帮忙检查一下LM5069电路这样设计是否合理,输入和输出用的二极管型号是B370-B3100,厂家为DIODES。MOS管型号是IRF540NSPBF,厂家为International Rectifier。附件放了电路设计的PDF文档和设计参数表格,谢谢!

Other Parts Discussed in Thread: LM5020 如题,想用LM5020-1驱动变压器做DCDC反激式电源,但看了LM5020的数据手册里的典型应用电路,不知道变压器辅助绕组输出的参数应该是多少,如下图红色方框圈到的地方,求助:辅助绕组输出电压和电流应该为多少。
附件是TI官方LM5020数据手册。
