● Description

ROHM’s high efficiency step-down switching regulator BD9111NV is a power supply designed to produce a low voltage including 3.3 volts from 5 volts power supply line. Offers high efficiency with our original pulse skip control technology and 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) and SLLMTM (Simple Light Load Mode)

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
