3-12V 0.6A 1ch Boost converter - BD8314NUV

ROHM’s 2.5 A/1.2 MHz step-up switching regulator BD8314NUV generates step-up output including 8 V or 10 V from 4 batteries, batteries such as Li1cell,Li2cell etc. or a 5 V fixed power supply line. This IC allows easy production of small and a wide range of output current, and is equipped with an external coil/capacitor downsized by high frequency operation of 1.2 MHz, built-in 2.5 A rated 80 mO Nch FET SW, and flexible phase compensation system on board.

* This is a standard-grade product.
