Unfortunately LTM8049 is not a good choice for this application. LTM8049 's max Vin is only up to 20 V.
I would suggest looking at LT8471 for your particular application
1. Paralleled LTM8045's will not share current. For higher power, you can use LTM8049, and that can be setup to share.
I d need to output +24.5V and -24.5V from the LTM8049.
The 24.5V output works fine but the -24.5V one is totally inoperative. All what I get is -6.8 V when setting up -24.5 V.
294 kOhms is my resistance to set the voltage and 53k6 my resistance to set…
Regarding table 1 of datasheet, is the value of capacitors decided by taking the characteristics of dc bias for MLCC into consideration ?
Indeed it should regulate +12V and -12V with an input of 12V. I would suggest you to use the components used on the demo board (DC2244A) as it has the same outputs that you are trying to achieve
I want to use the LTM8049 to generate 6.3V and 4.3 V from a 12 V input. According to the LTM8049 datasheet, a very large output capacitor is required for the lower output voltages.
At the moment I am using a 2 x 10 uF X7R capacitors at the 6.3V…
I can't find any information on the LTM8049's datasheet about its minimum output current. What will happen when the uModule is under extremely light load (10mA) ?
Reliability data for all legacy LTC products are linked to the product page in the Documentation section.
The LT8330 makes a good positive and negative output DC-DC converter for signal processing circuits, especially since the LT8330 is designed to be efficient even at light loads. The positive and negative idea can apply to the other inverting converter circuits…
