LMH6525: Can this part be used with a 405nm laser diode

David Blankenbeckler

Part Number: LMH6525

Can this part be used with a 405nm laser diode (forward voltage 6-7V)?

If this part cannot be used with a 405nm laser diode is there another part available that will work with a 405nm laser diode.

I need capability for high power pulses as well as CW mode (e.g. like a Blu-ray writer).

Thanks.

Hello David,

This part can not drive laser diodes up to a forward voltage of 6-7V. The max it can output is around 4.3V. I will have to check if we have a product that will fit your requirements, and will get back to you by tomorrow.

Thank you,

Sima

Hi David and Sima,

Please refer to the link below for LED drivers which may meet your requirements.

ONET line of products do not 6-7V forward voltage that you require. These are also used for 155Mbps and higher data rates. Please below note a link to the ONET products:
