Switching Regulator Question

CEI,

The ADP1621 boost controller can be used as you describe for an asynchronous design (one switch, one diode) with or without isolation.

The ADP1828 buck controller can be used as a 2 low side switch flyback if you do not need isolation.

Here is an example of the ADP1621 design

• PRD1205: Quasi-Isolated Flyback (pdf, 0)
  This is a 10V - 14 input isolated flyback converter which uses the ADP1621 controller and an AD8691 operational amplifier. The target application of this converter is for powering a portable media player from the accessory power outlet of an automobile.
