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. At moderate to heavy loads, this part operates in PWM mode with a constant switching frequency of 20MHz.
