Digital High Voltage Constant Current Laser Driver

This series of digital laser drivres have all the valuable and important features, but are often difficult to achieve simultaneously such as: wide input and output voltage range, high output current capability, high efficiency, low output noise (but it has an output 6mVp-p ripple voltage at 500kHz), wide modulation bandwidth, and small size. The wide output voltage range, 0.1VVPS ~ 0.8VVPS, allows driving one or multiple serial laser diodes at the same time, for up to 5A and 15A of well controlled current at high efficiency. The extremely low noise between DC ~ 10kHz and low DC current drift make it ideal for driving diode pumped single mode laser diodes to achieve mode-hop-free and narrow optical wavelength drift, thus, long coherent length.
