SC221
Product is not recommended for new design.
The SC221 is a 20MHz X-EMI®(1)-enabled step-down regulator optimized for power low voltage rails from 2.7 to 5.5V input voltage. X-EMI inductor technology enables inductors to be drawn directly on the PC board. This technology meets or exceeds the EMI performance of chip inductors and eliminates the need for discrete inductors.
