Figure 24. 10 V/1.0 A Constant−Voltage Constant−Current Regulator
Figure 25. Output Load Regulation
Figure 24 shows the MC33341 configured as a source high−side constant−voltage constant−current regulator. The regulator is designed fo
r
an output voltage of 10 V at 1.0 A. Figure 25 shows the regulator’s output characteristics as the load is varied. Source return low−side, load
high−side, and load low−side configurations will each exhibit a nearly identical load regulation characteristic. A heatsink is required for the
MTP2955 series pass element.

Figure 26. Constant−Current Constant−Voltage Switch Mode Charger
Figure 26 shows that the MC33341 can be configured as a high−side constant−current constant−voltage switch mode charger. This circu
it
operates as a step down converter. With a nominal input voltage and output load current as stated above, the switching frequency i
s
approximately 28 kHz with and an associated conversion efficiency of 86 percent. The switching frequency will vary with changes in inpu
t
voltage and load current.
