LED2000DR led driver mcu in which i functioned the circuit for 1.4 Amps. But i got the output only 0.3 Amps only. Output voltage is still 5v But current is very less.

Hi Friends,

I have designed a circuit using LED2000DR for a project. I given 5V input to the circuit and i got 5V same as given in the input. The circuit i designed for 1.4 Amps But i got the 0.3Amps only. I am confused that why the current is low. But led works and voltage is 5V. That's ok. I changed the current sense resistor and also the MCU but no use nothing changed.

Anyone faced similar issues like this. I am totally stuck with this issue. Anyone help me to solve the issue and attain the desired output.

I just followed the circuit that taken from the "st design suite". Any help will be appreciated.

Thanks
