with Built-in Power MOSFET
BD9106FVM,BD9107FVM,BD9109FVM,BD9110NV,BD9120HFN
No.09027EAT33
●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
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 SLLM^TM (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
MSOP8 (BD9106FVM,BD9107FVM,BD9109FVM), HSON8 (BD9120HFN), SON008V5060 (BD9110NV)
