• Bad battery indicate of LTC3558

    Hi,

    I'm using LTC3558 on my project. Sometimes, I have confirmed bad battery indicate on CHRG pin within 10min.

    According to the datasheet, In case of bad battery, LTC3558 is indicated more than 30min later.

    Could you teach me why CHRG pin indicate…

  • LTC3558 - Type III Compensation

    Hello,

    We were using the LTC3558 earlier to generate 1.8V and 3.3V. The 3.3V is from VOUT2 with all the resistor and capacitors as specified in the data sheet.

    Now, we changed the circuit to generate 5V from VOUT2 and have a different circuit for the…

  • RE: LTC3558 Type III compensation for 5V

    Looks like all of the messy math does not include Rfb. So if you use the example and just adjust Rfb, all other component can remain the same.

  • LTC3558按照数据手册中典型应用设计输出电压低

    这是设计的原理图,理想情况下输出应该是3.3V,但是实际上静态时输出的电压是3.19V,而带载时(偏心马达)输出降到了2.5V。这是什么情况呢?是不是环路补偿的部分出了问题?

  • Not use buck regulator of LTC3558

    Hi,

    When not using the buck regulator of LTC3558, no problem to connect these related pins as follows?

    PNIN1=SW1=FB1=EN1="L" (=GND)

    Thanks,

  • LTC3558 has the same output with OUT1,OUT2,BATTERY

    I have make a PCB from datesheet. but the chip can't output a correct value with programing,FB1 with the voltage of 0V,and FB2 is 3.6V, my input voltage is 5.17V,

    please could help mo how can i do to found problem whit my engineering

  • LTC3558基准电源不准

    朋友们大家好,最近在做一块LTC3558的板子做测试,发现输出的电压和设置的编程输出电压相差很大,FB1的基准电压为0.25V,FB2的基准电压为0.11V,板子原理图和官方给出的DEMO板子基本是一致的,但是现在还没找到问题到底出在了哪里?

    希望看到的朋友们能够提出大家的建议和意见,我们会虚心向大家学习,同时非常高兴大家在这里展开讨论

  • LIPO Power Management

    Hi,

    Facing issues with LIPO battery charging while using LTC3558.
    Battery fault occurs while charging a good battery which was discharged (below 2.5V).

    Would like to know Is it possible to

    1. Increase the charge current ,in LTC3558, to a higher…

  • Alternative to ADP5360

    Hello everyone,

    I am currently designing a prototype with the nRF9160 chip and a 3,7V battery.

    The development board, which I use as a reference, uses the ADP5360 for battery and power management.

    The problem is that the ADP5360 only comes in a tiny 32…
