Reseting problem i LYT 5228D_Line Sense Pin_Reg
we are using LYT5228D IC for our LED lighting application. We are using the recommended 2.4Mohm+2Mohm resistors at the line sensing pin of the IC. It is denoted that it can support a input voltage threshold of 260V (90-308V) as given in its datasheet. But as we have tested the circuit with the load whenever the input voltage increases beyond 220V the IC resets the load and it powers the load after some seconds. The changes we have done in our circuit are changing the values for resistors R1 and R2 (R1 changed from 732Kohm to 1Mohm : R2 changed from 56.2kohm to 47Kohm).SO
i)can i get any reference(study material) regarding the value of resistors R1,R2,R4 and R5 .How to calculate the resistors used there?
ii)can someone give us a solution regarding the resetting problem?
I have attached our circuit recommended from PI integrations .Log in or register to post comments
