As an approximation, the RMS current in C
For worst-case situations, the RMS current in the C
coupling capacitor is equal to 2A x (4.2V / 12V)
1.18A. The current rating for small multi-layer ceramic
capacitors is typically much higher than 1.18A. For
higher power applications, it may be necessary to use
multiple capacitors in parallel to keep the RMS current
within ratings.

CONCLUSION
For applications that require intelligent power manage-
ment solutions like battery chargers, the combination of
a microcontroller and MCP1631 high-speed PWM is
very powerful. It brings the programmability benefits of
the microcontroller and adds the performance of a
high-speed analog PWM. The analog PWM will
respond to changes in input voltage and output current
very quickly. No code or execution time is necessary to
regulate or protect the circuit. The microcontroller is
used for programmability, establishing charge profile
conditions and monitoring the circuit for fault conditions
and taking the appropriate action, in the event of a
specific fault.
