ROHM’s buck converter BD91501MUV is a 2ch output

power supply designed to produce a low voltage

including 2.55V/0.4A and 1.8V/0.3A from 3.3V 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.

 Output voltage accuracy

 Switching frequency:

 Low Voltage Detection:

 Maximum on duty:



Operating temperature range:

-30℃ to +105℃

●Package

(Typ.) (Max.)

VQFN016V3030:

3.00mm × 3.00 × 1.00mm

●Features



Offers fast transient response with current mode

PWM control system.



Offers highly efficiency for all load range with

synchronous rectifier (Pch/Nch FET) and SLLM^TM

(Simple Light Load Mode)



Incorporates soft start function

Incorporates thermal protection and UVLO function

Incorporates short-current protection with timer

latch



Incorporates shutdown function Icc=0µA (Typ.)

Full 100% Duty function

2ch output power supply (2.55V, 1.8V)

2ch output ON/OFF individual control

Employs small surface mount package:
