Constant Current Control for
DC-DC Converters
Introduction ................................................................1 The pull up / down network (Ru, Rd and Rs) allows the
error amplifier to vary the output of the converter by trim-

Power Limitations .......................................................1 driven too high or too low.
Voltage Loop Stability ................................................2 The diode in series with the positive lead isolates the
Current Loop Compensat
