Single-chip Type with Built-in FET Switching Regulators

Low Noise High Efficiency

Step-down Switching Regulator

with Built-in Power MOSFET

BD8960NV

No.10027EBT21

●Description

ROHM’s high efficiency step-down switching regulator BD8960NV is a power supply designed to produce a low voltage

including 1 volts from 5.5/3.3 volts power supply line. Offers high efficiency with synchronous rectifier. Employs a current

mode control system to provide faster transient response to sudden change in load.

●Features

1) Offers fast transient response with current mode PWM control system.

2) Offers highly efficiency for all load range with synchronous rectifier (Nch/Pch FET)

3) Incorporates soft-start function.

4) Incorporates thermal protection and ULVO functions.

5) Incorporates short-current protection circuit with time delay function.

6) Incorporates shutdown function

7) Employs small surface mount package : SON008V5060

●Applications

Power supply for LSI including DSP, Micro computer and ASIC

●Line up
