With the advent of the switching regulator platform, not only simplifies the circuit board layout, easier to use, designed to more easily the linear voltage regulator to replace the more efficient switching regulator. In addition, the chip loop compensation and programmable output voltage to save the external control components and programming resistors, further reducing PCB space.

New switching regulator platform, a very small, simple, high cost of power management solutions. Synchronous rectifier buck regulator, the PWM switching frequency of 3.5MHz, the output current of 500mA, efficiency as high as 94%. In addition, the chip loop compensation and programmable output voltage to save the external control components and programming resistors, further reducing PCB space. Combination of high integration and ultra-small packaging technology, effectively reduce the occupied area to 14 mm2, provides designers with a more efficient switching regulator, can serve as a LDO alternatives.

The switching regulator platform design is very simple, only two external capacitors: one for input decoupling, one for the output filter. In addition to work with high efficiency, the SC202 with automatic energy saving function can be reduces quiescent current to 38μA (under normal circumstances), and thus maintain high efficiency in light load.
