3.0V to 12V, Integrated 2.5A MOSFET 1ch Boost Converter
BD8314NUV
General Description BD8314NUV is a high-efficiency step-up switching regulator with built-in power MOSFET that can output 8V or 10V from a 4-battery voltage supply such as Li1cell, Li2cell, or a 5V fixed power supply line. The built-in 80mΩ N-Channel FET switch is capable of handling output current up to 2.5A (DC). This IC has a flexible phase compensation system and a switching frequency of 1.2MHz allowing the use of smaller external output inductor and capacitor making the construction of a compact power supply really easy.
