Beschreibung

BD9A300MUV is a synchronous buck switching
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
transie

Merkmale
