    We are using LM3488MM IC for booster purpose. We are setting the output voltage 13.5 @ 3A. and attached the design circuit also.

    The problem is when we are increasing the input voltgae 6 to 8.3V. The ouput voltage Remains constant @ 13.5V at no load condition.

    If I give output load 100mA the output voltage drops at that time the input voltage is 6 to 7.4V. That is the switcher not switching proberly. The input voltage comes at output voltage. When I am increasing Input voltage above 7.4V the output voltage remains constnt at 13.5 V @100mA load.

    I need what is the problem in the input voltage 6 to 7.4V when iam giving minimum load.

    If it is design problem please rectify and tell me
