Semtech SC220Q

20MHz, 650mA, X-EMI™-Enabled Synchronous Step-Down Regulator

Add to Watch List

The SC220/Q 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.

Note 1: Purchase of SC220/Q includes royalty-free right to use X-EMI™ inductor technology with no additional cost.
