The PCO-6130 is a compact, OEM-style high power pulsed current source designed to drive diode lasers, bars and arrays in pulsed, QCW or CW modes. It delivers output current variable from 1A to 125A, pulse widths variable from <600ns to DC, and pulse repetition frequencies variable from single-shot to 250KHz at duty cycles up to 100%.
The PCO-6130 features a user-adjustable variable rise time control. This innovative feature allows the user to adjust the rise time within a range of <200ns to >5µs by means of a PCB-mounted potentiometer, to optimize the driver’s rise time for the user’s application.
The PCO-6130 is based on a hysteretic, average current, switch-mode regulator. This type of regulator is a variable frequency, variable pulse width design which maintains current in an energy storage inductor between a minimum and maximum level. The ripple is limited to the minimum and maximum current determined by the hysteretic controller. The regulator is started when the TTL "enable" line is taken high and runs as long as the enable is high. The use of the hysteretic regulator provides a large input range and high efficiency.
