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. This high switching frequency
offers the advantages of using small and low cost
external components like a 1μF external capacitor and a
small 220nH inductor (including X-EMITM PCB trace
inductors).
The device provides adjustable output voltages down to
1.0V and an output current up to 650mA. An EN pin can
be used to synchronize to an external source and includes
de-glitching to reduce noise sensitivity.
The SC220/Q is available in SOIC 8 lead package.
The SC220Q is an AEC-Q100 qualified version.
