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

BD9134MUV

No.09027EBT15

●Description

ROHM’s high efficiency step-down switching regulator BD9134MUV is a power supply designed to produce 3.3 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/Nch FET)

and SLLM^TM(Simple Light Load Mode)

3) Incorporates soft-start function.

4) Incorporates thermal protection and UVLO 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

●Use

Power supply for LSI including DSP, Micro computer and ASIC

●Absolute Maximum Rating (Ta=25℃)
