ROHM
ROHM Semiconductor
BD9122GUL 2.5V to 5.5V, 0.3A 1ch Synchronous Buck Converter integrated FET

General Description
ROHM’s high efficiency step-down switching regulator (BD9122GUL) is a 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 SLLM™
   (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

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