ltm4622a

HI,

Is there anybody who can give me some clues on the questions below? Thanks in advance.

(1) The minimum output voltage of LTM4622A is 1.5V. Can it output 1.2V ?

(2) If we replace the 40.2k resistor with 60.4k, can Vout1 output 1.2V?

If so, what will be the possible problem with long-term use of 60.4k resistor under this condition?

  • Hi,

    It is not recommended to operate outside of the datasheet spec. Depending on other settings, you may run into minimum on-time issues, issues caused by size of inductor ripple, and other unforeseen issues due to being outside of the datasheet spec. 

    I would recommend the LTM4622 for operating at 1.2Vo. It is very similar to the LTM4622A, and it is able to run at 1.2Vo.
