Hi,
	I have a question. When should one consider choosing a switching
power supply over a standard AC/DC + CAP + Voltage regulator?

	I have a product that has a motor (12V and 2A max) and a control
circuitry (5V and <100mA). I have a transformer with 2 windings and two
separated power supplies (meaning 2 rectifiers, 2 capacitors, and actually 1
regulator, since the motor needs no regulation on this application).

	I would like to know why should I want to or consider to change to a
switching power supply... is it usually more expensive, right?

Thanks,

Mauricio Jancic
