High power laser constant current drive circuit
Source: InternetPublisher:JFET Keywords: Laser constant current drive circuit Updated: 2024/07/18
High-power laser constant current drive circuit, this circuit can drive the maximum current up to 1.2A. It is necessary to add a heat sink to Q1. The op amp can use LM358. Of course, using a rail-to-rail op amp may be better. Similarly, adjust the position of the R4 contact to change the size of the laser current.
