Single-chip Type with Built-in FET Switching Regulator Series
Output 2A or More High-efficiency
Step-down Switching Regulator
with Built-in Power MOSFET
BD9130EFJ
No.09027EAT30
Description
ROHM’s high efficiency step-down switching regulator BD9130EFJ is a power supply designed to produce a low voltage
including 1 volts from 5.5/3.3 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 SLLMTM(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 : HTSOP-J8
