The ML6553 switching regulator is designed to convert voltage supplies ranging from 2.0V to 3.6V into a desired output voltage or termination voltage for various applications. The ML6553 can be implemented to produce regulated output voltages in two different modes. In the default mode, the output is 50% of voltage applied to VCCQ. The switching regulator is capable of sourcing or sinking up to 1A of current.
