I am currently using TPS61240 as a boost converter for my project. As i did not have any sample previously so there was no way I could test it. I ordered the IC and placed it on my final PCB directly. PCB layout and external components are according to the datasheets. I ran continuity and input voltage measurement test. There is no problem in PCB and Input voltage. But I am not getting 5 volts from the IC. I am in great trouble. Any suggestion would be appreciated. Thanks in advance.
Here is the PCB layout.
and here is the Schematics
Answer
I have added a 6.3V 100uf capacitor parallel to the 4.7uf ceramic capacitor at the output of the BOOST converter IC. Now Its working fine, and I am able to get 5.22 voltage from the input 3.3v.
