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
BD9152MUV
No.10027ECT14
●Description
ROHM’s high efficiency dual step-down switching regulator BD9152MUV is a power supply designed to produce a low
voltage including 3.3,0.8 volts from 5.5/4.5 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 (Pch/Nch 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 Icc=0μA(Typ.)
7) Employs small surface mount package : VQFN020V4040
●Application
Power supply for LSI including DSP, Micro computer and ASIC
●Absolute Maximum Rating (Ta=25℃)
