BD9120HFN Datasheet PDF - ROHM Semiconductor

●General Description

●ROHM’s high efficiency step-down switching regulators (BD9106FVM, BD9107FVM, BD9109FVM, BD9110NV, BD9120HFN) are the power supply designed to produce a low voltage including 1 volts from 5/3.3 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

●Offers fast transient response with current mode PWM control system.

●Offers highly efficiency for all load range with synchronous rectifier (Nch/Pch FET) and SLLMTM (Simple Light Load Mode)

●Incorporates soft-start function.

●Incorporates thermal protection and ULVO functions.

●Incorporates short-current protection circuit with time delay function.

●Incorporates shutdown function

●Application

●Power supply for LSI including DSP, Micro computer and ASIC
