Micrel has increased the operating frequency of its SuperSwitcher SO-8 buck regulator to 500 kHz. The MIC4690, is the newest member of Micrel Semiconductor's SuperSwitcher family.
Micrel's SuperSwitcher family has evolved from 50 kHz, to 200 kHz, and now to 500 kHz. The higher operating frequency allows the use of smaller inductors and capacitors, saving designers valuable board space and cost. The MIC4690 boasts a wide input voltage range of 4 V to 34 V, and a high 1,3 A output current. Only 4 external components are required with the MIC4690, making it a very simple-to-use solution.
