Datasheet
2.7V to 5.5V Input, 1A Integrated MOSFET
Single Synchronous Buck DC/DC Converter
BD9A100MUV
General Description
BD9A100MUV is a synchronous buck switching
regulator with built-in low on-resistance power MOSFETs.
It is capable of providing current up to 1A.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.
