Semtech SC220

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

The SC220 is a 20MHz X-EMI™(1)-enabled step-down regulator optimized for powering 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 includes royalty-free rights to use X-EMI™ inductor technology with no additional cost.
