The PCO-6131 features a user-adjustable variable rise time control. This innovative feature allows the user to adjust the rise time within a range of 2.5μs by means of a PCB-mounted potentiometer, to optimize the driver’s rise time for the user’s application. The PCO-6131 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. This architecture provides a high performance driver in a small form factor, with high operating efficiency and low stored energy. At 125A output current, the stored energy in the driver is approximately 7 Joules, dramatically lower than the stored energy in comparable linear current sources.
