Dear Sir,
We designed PCB for Constant output Voltage and constant current 9W LED driver. The following are the 9W LED driver specifications:
|
Input |
|
|
Operating Voltage Range |
120 to 270 VAC |
|
Operating Frequency Range |
48 to 62Hz |
|
Power factor |
>0.95 |
|
Harmonic Distortion (THD) |
<12% |
|
Isolation |
Isolated input and output ground are to separate |
|
Output |
|
|
Nominal Output Voltage |
30Vdc |
|
Output Current |
300mA |
|
CV/CC |
Constant output Voltage and constant current |
We designed 9W LED driver PCB with IC part number: TPS92210, make: TI. We followed and using TI reference guide TPS92210-PMP6001 for the above driver.
It was not working and observed, output voltage of LED driver not coming, when the input supply applied.
Please find the attached schematic for your reference.
Please suggest for further action.
