Description

BD9B300MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. This IC, which is capable of providing current up to 3A, features fast transient response by employing constant on-time control system. It offers high oscillating frequency at low inductance. With its original constant on-time control method which operates low consumption at light load, this product is ideal for equipment and devices that demand minimal standby power consumption.

Features

  • Synchronous Single DC/DC Converter
  • Constant on-time control suitable to Deep-SLLM
  • Over Current Protection
  • Short Circuit Protection
  • Thermal Shutdown Protection
  • Under Voltage Lockout Protection
  • Adjustable Soft Start
  • Power Good Output
  • VQFN016V3030 Package (backside heat dissipation)

Typical applications

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