APPLICATION NOTES

VOUT RISE TIME CONTROL

The output rise time of the MSK6000RH and the associated

surge currents can be controlled over a wide range using a few

external components as shown in the smplified schematic be-

low. Power dissipation in the MSK6000RH can increase during

turn on or bus voltage transients and should be considered. The

circuit below performs the rise time control function by control-

ling the voltage drop VR across RBAL. Assuming a constant cur-

rent to linearly change the output capacitance, the MSK6000RH

rise time is approximated by the following equation:

dVOUT

dt

=

VRBAL

ßQ1 x RBAL x CFB

Where VRBAL=VC - VTHRESHOLD
