MOTOROLA ANALOG IC DEVICE DATA
Figure 25. Constant–Current Constant–Voltage Switch Mode Charger
Figure 25 shows that the MC33341 can be configured as a high–side constant–current constant–voltage switch mode charger.
This circuit operates as a step down converter. With a nominal input voltage and output load current as stated above, the
switching frequency is approximately 28 kHz with and an associated conversion efficiency of 86 percent. The switching fre-
quency will vary with changes in input voltage and load current.
