SC122数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The SC122 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.
