TEA1721AT chipset based non-isolated power supply,

Discussion created by Hitesh Barot on May 8, 2017

Hi There,

i am  using your TEA1721AT chipset in some of current designs for non-isolated power supply, it was working fine with my previous design but for new design i used the same circuit but the layout is bit change , now i am the same 12V output as i was getting previously but as i put any load (within the limit of 50mA) the 12V gets down and fluctuate , it seems like consuming more current . i followed the circuit given into UM 10522 for buck converter only.  please help me out. thanks in advance
Thanking you,
