●General Description

●Key Specifications

 Input voltage range

BD9120HFN:

ROHM’s high efficiency step-down switching regulators

(BD9106FVM,BD9107FVM,BD9109FVM,BD9110NV,B

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.
