ROHM’s 1.2A/1.0 MHz synchronous step-down switching regulator BD8313HFN-TR produces step-down output including 1.2, 1.8, 3.3, or 5 V from 4 batteries, batteries such as Li2cell or Li3cell, etc. or a 5V/12V fixed power supply line. This IC allows easy production of small power supply by a wide range of external constants, and is equipped with an external coil/capacitor downsized by high frequency operation of 1.0 MHz, built-in synchronous rectification SW capable of withstanding 15 V, and flexible phase compensation system on board.
