HI Subash,

Is a battery or simulated battery attached to BAT? If not, if you remove the /CE pin shunt, does the output settle to ~3.5V?

Regards,

Jeff

Hi Subash,

Are the ILIM_HIZ jumpers (either JP13 or JP14) installed to either set either 1.5A or 0.5A input current limit? Are you following the EVM user's guide test procedure?

Jeff

Subash,

Can you send a picture of you test setup? What is the current limit of your power source connected at the EVM's VIN pin?

Regards,

Jeff
