General Description
BD8311NUV 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 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. 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.

FEATUREs
■ Built-In 2.5A/14V N-Channel FET Switch
■ On-Chip Phase Compensation Between Input and Output of ERROR AMP.
■ Output Current:
    ➤ 600mA at 10V (3.5V to 10V input)
    ➤ 800mA at 8V (3.5V to 8V input)
■ Built-In Soft-Start Function.
■ Built-In Timer Latch System for Short Circuit Protection Function.

APPLICATION
    General Portable Equipment like DSC/DVC Powered by 4 dry Batteries or Li2cell
