The TTL frequency of the stage llight  on the market is generally within 20 Khz, which can not meet the high-frequency output requirements of 3D printing. The waveform of this circuit is stable as high as 150 Khz frequency, and uses dual fan input. It is suitable for high-end laser driver with high efficiency and low heating. It is one of the recommended driving circuits for fiber green.

It is suitable for various stage lights, DIY engraving machine and 3D printer laser module driver.
