Splet10. sep. 2007 · CURRENT MODE CONTROL While designing a buck converter, there is always a trade-off between the inductor and the capacitor size selection. A larger inductor value means numerous turns to the magnetic core, but less ripple current (<10% of full load current) is seen by the output capacitor; therefore, the loss in the inductor increases.

SpletThe charge pump requires no external components and allows operation from supplies as low as 2.7 V.
