• RE: ltm4622a

    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. 

  • LTM4622A voltage regulation

    I'm having trouble getting the LTM4622A to regulate at the right voltage. It's putting out about 2.9V rather than the expected 5V. It's set up in the following way:

    Parallel operation
    Input: 10V (going to all VIN pins)
    Desired output: 5V (both…

  • Questions about LTM4622A

    Hi AD team, please answer the following questions:

    1. The LTM4622A datasheet says (in the Description section):

    Fault protection features include input overvoltage, output overcurrent and overtemperature protection.

    However, no explanation is given…

  • LTM4622A parallel combination issue

    Dear Sir/Mam,

    Please find the attached schematic for your reference.

    Input Voltage: 16VDC

    Output Voltage Required: 12VDC/4A

    I have designed a schematic as per figure No: 28 in the LTM4622A datasheet.

    But when I connect the input supply, it get burned…

  • RE: There are terrible noise (sine wave) on the AD5560 FORCE OUTPUT while operating

    If you can check the outputs of the LTM4622A and the rails look fine (ie stable switching) then maybe the issue is not related to the LTM4622A. You may also check LTM4622A design in LTpowerCAD to estimate if the loop has sufficient stability margins.

  • LTM4622 Datasheet Typing Error

    Dear All:

    I check LTM4622A Datasheet  Page 19 Table 5 & Table 6 to comparison Page 18 Figure 21~Figure 23 in conclusion Table 5 Vin need show 12V ,Table 6 Vin need show 16V .It's need to update datasheet , Thanks

  • LT1185 positive output regulator with floating input

    Dear sir or madam

    I'm confused about how to design a positive output with LT1185 as it mentioned in its datasheet .

    I've already had a DCDC ,(LTM4622A), which generates both 8.5V(adjustable) and 3.5V(adjustable) . Now , I'm going to insert a LDO…

  • RE: LTM4622 Output jumps to 12V

    Thank you so much for your input SYoung! It is very insightful. Unfortunately, I did not break out the freq pin in my design, and as it is in the center of the package, I cannot access it.  At your request, I loaded the LTM4622 today with a 5ohm power…

  • RE: inductor current ripple in uModules

    Hi Shimon, 

    Keeping the inductor ripple within a reasonable range helps guide the design to have sufficiently large current sense signal for proper operation, but not too large so that you may potentially trigger reverse current threshold at light load…
