Selecting the controller IC
The desired features one might look for in a buck controller IC would be:
1. Ability to operate directly from the input voltage.
2. Pulse-to-pulse overcurrent limiting.
3. Totem-pole MOSFET drivers.
There are many buck controller ICs on the market, but the one that was chosen
is the UC3873. The internal reference presented to the voltage error amplifier
is 1.50V+/- 2 percent. ...
