Hi,

When I turn on the device with full load condition (1.5A) the unit is going to some kind of protection but when I turn on the device without load than output is perfect even after loading full load (1.5A), I need to make the device on with full load on condition.

Pl resolve this issue as soon as possible

Thanking You.

Hi CS Power,

Thank you for reaching out.

I think the problem is more wrt to noise coupling to the CS pin when full load is turned ON.

Please observe the CS pin with and without load. It might be necessary to increase the capacitance here. Maybe check with upto 120pf and it should be as close as possible to this pin.

Regards,

Harish
