Figure 26 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 frequency will vary with changes in input
voltage and load current.
