Power Switching Regulators
Easier, Faster Power Designs and Fewer External Components. . .
Power Regulators from ON Semiconductor offer the simplest, most economical way to design a power supply compliant with stringent
requirements on standby power. These highly integrated solutions reduce system size and external component count to a minimum. The
Dynamic Self Supply feature can even eliminate the auxiliary winding of the transformer. The design of your power supply can be done in
minutes – drastically reducing your time-to-market.
