The SC122ULTRT is a high efficiency, low noise, synchronous step-up DC-DC converter. It produces a fixed 3.3V output from a single cell alkaline or NiMH battery. It features an internal 1.2A switch and synchronous rectifier to achieve high efficiency and to eliminate the need for an external Schottky diode.
