General Description
Key Specifications
BD9A300MUV is
a
synchronous buck switching
Input Voltage Range:
Output Voltage Range:
Average Output Current:
Switching Frequency:
High-Side MOSFET On-Resistance: 60mΩ(Typ)
Low-Side MOSFET On-Resistance: 60mΩ(Typ)
2.7V to 5.5V
0.8V to VPVIN×0.7V
3A(Max)
regulator with built-in low on-resistance power MOSFETs.
It is capable of providing current up to 3A.The SLLMTM
control provides excellent efficiency characteristics in
light-load conditions which make the product ideal for
equipment and devices that demand minimal standby
power consumption. The oscillating frequency is high at
1MHz using a small value of inductance. It is a current
mode control DC/DC converter and features high-speed
transient response. Phase compensation can also be set
easily.
