Single-chip built-in FET type Switching Regulator Series
Output 1.5A or Less High Efficiency
Step-down Switching Regulators
with Built-in Power MOSFET
BD9102FVM, BD9104FVM, BD9106FVM
No.09027EAT34
Description
ROHM’s high efficiency step-down switching regulator (BD9102FVM, BD9104FVM, BD9106FVM) is a power supply
designed to produce a low voltage including 1.24 volts from 5 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 MSOP8
Use
Power supply for HDD, power supply for portable electronic devices like PDA, and power supply for LSI including CPU and
ASIC
