Datasheet
1.8V to 5.5V, Integrated 2.0A MOSFET 1ch
Buck-Boost Converter
BD8306MUV
General Description
ROHM’s highly-efficient buck-boost converter
BD8306MUV produces buck-boost output voltage
including 3.3 V from two-cell or three-cell alkaline
battery, or one-cell lithium-ion battery with just one
inductor. This IC adopts the original buck-boost drive
system and creates a more efficient power supply than
the conventional SEPIC-system or H-bridge system
switching regulators.
Features
Highly-Efficient Buck-Boost DC/DC Converter
Constructed with just one Inductor.
Maximum output current changes depending on the
input and output voltages. Input current for PVCC
terminal should be less than 2.0A including the DC
current and ripple current of the inductor. Please
refer to Figure 25 and Figure 34 for details about
the maximum output current at 3.3V and 5.0V
output.
Incorporates a Soft-Start Function.
Incorporates a Timer Latch System with Short
Protection Function.

(Note 1) When mounted on 74.2x74.2x1.6mm and operated over 25°C Pd reduces by 4.96mW/°C.
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
