SC220 x SC220Q
POWER MANAGEMENT Features
20MHz, 650mA, X-EMI™-Enabled Synchronous Step-Down
Regulator
Description
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.
The SC220/Q uses a unique constant frequency, selfoscillating control loop architecture to provide excellent transient performance.
Under light loads, the device operates in Power Save mode(PSAVE) maintaining a typical quiescent current of 19µA.
