Quick Detail:


1ch DC/DC Converter Controller IC with Built-in Synchronous rectifier





ROHM’s high efficiency step-down switching regulators


D9120HFN) 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.





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


Incorporates short-current protection circuit with

time delay function.

Incorporates shutdown function
