This is the product guarantees long time support in
Industrial market. BD9A301MUV-LB 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 transient response. Phase
compensation can also be set easily.


  • Long Time Support Product for Industrial Application
