2.3.3 Potentiometers

This section describes the jumpers:

  • Low (R15) is the low-level adjustment of the load transient. Turning the potentiometer clockwise raises the low level.
  • High (R23) is the high-level adjustment of the load transient. Turning the potentiometer clockwise raises the high level.
  • Pos Slew (R12) is the positive slew rate adjustment. Turning the potentiometer clockwise increases the rising transition time.
  • Neg Slew (R58) is the negative slew rate adjustment. Turning the potentiometer clockwise increases the falling transition time.
  • Settling (R43) is the settling time adjust. Turning the potentiometer clockwise dampens the oscillations by increasing the time required for the transition to settle to a steady state value.
  • Width (R47) is the pulse width adjustment of the high level. Turning the potentiometer clockwise increases the pulse width.
  • Delay (R46) is the delay adjustment of the high level relative to the period. Turning the potentiometer clockwise increases the delay time.
  • Period (R36) is the period adjustment of the low level. Turning the potentiometer clockwise increases the period.
