... General Description The RT9223 is a high efficiency synchronous switching regulator for modern CPU application. The output is controlled by a 5-bit DAC programmed from 1.3V to 2.05V in 0.05V steps and from 2.1V to 3.5V in 0.1V increments. The switching controller drivers two N-MOSFETs at 200KHz frequency and provides an optimal solution for size, efficiency and cost in any application circuits ...
