with Built-in Power MOSFET

No.10027ECT03

BD8311NUV

●Description

ROHM’s High-efficiency Step-up Switching Regulator Built-in Power MOSFET BD8311NUV generates step-up output

including 8 V or 10 V from 4 batteries, batteries such as 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 mΩ Nch FET SW, and flexible phase

compensation system on board.

●Features

1) Incorporates Nch FET capable of withstanding 2.5 A/14 V.

2) Incorporates phase compensation device between input and output of ERROR AMP.

3) Small coils and capacitors to be used by high frequency operation of 1.2 MHz

4) Input voltage 3.5 V – 11 V

5) Output current

600 mA (3.5 V – 10 V) at 10 V

800 mA (3.5 V – 8 V) at 8 V

6) Incorporates soft-start function.

7) Incorporates timer latch system short protecting function.

8) As small as 3 mm², SON 10-pin package

VSON010V3030

●Application

General portable equipment like DSC/DVC powered by 4 dry batteries or Li2cell
