Description

BD9A400MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. It is capable of providing current up to 4A.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

Features

  • Synchronous Single DC/DC Converter.
  • SLLMTM (Simple Light Load Mode) Control.
  • Over Current Protection.
  • Short Circuit Protection.
  • Thermal Shutdown Protection.
  • Under Voltage Lockout Protection.
  • Adjustable Soft start Function.
  • Power Good Output.
  • VQFN016V3030 Package (Backside HeatDissipation)

Typical applications

  • Step-Down Power Supply for DSPs, FPGAs, Microprocessors, etc./ Distributed Power Supply, Secondary Power Supply
  • Laptop PCs/ Tablet PCs/ Servers/ LCD TVs/ Storage Devices (HDDs/SSDs)
  • Printers, OA Equipment/ Entertainment Devices
