Single-chip Type with Built-in FET Switching Regulator Series
Output 1.5A or Less High Efficiency
Step-down Switching Regulator
with Built-in Power MOSFET
BD9150MUV
●Description
ROHM’s high efficiency dual step-down switching regulator BD9150MUV is a 2ch output power supply designed to produce a
low voltage including 3.3,1.2 volts from 5.0 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 (Pch/Nch FET) and SLLM (Simple Light Load Mode)
3) 2ch output power supply.
4) Each of EN controls 2ch output.
5) Incorporates soft-start function.
6) Incorporates ULVO functions.
7) Incorporates thermal protection and short-current protection circuit with time delay function.
8) Incorporates shutdown function Icc=0μA(Typ.)
9) Output current max 1.5A/1.5A.
10)Employs small surface mount package : VQFN020V4040
●Use
Power supply for LSI including DSP, Micro computer and ASIC
