System Efficiency
Example Circuits
This circuit and the one featured on the front page have been
designed to deliver high current and high efficiency in a small
package, both in area and in height The tallest component in
this circuit is the inductor L1, which is 6mm tall. The com-
pensation has been designed to tolerate input voltages from
5 to 16V.
