Step-down Switching Regulator
with Built-in Power MOSFET
BD9150MUV
No.09027EAT13
âDescription
ROHMâs 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.
âFeatures
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
âUse
Power supply for LSI including DSP, Micro computer and ASIC
