Equation 5
In conclusion, the advantage of the linear charging approach is that the designer has direct
control of the charge current, and consequently the application can be very simple. The
drawback is the high power dissipation.
The advantage of the quasi-pulse charging method is that the power dissipated is
dramatically reduced. The drawback is that a dedicated upstream adapter is required.
