Description

BD9B500MUV is a synchronous buck switchingregulator with built-in low on-resistance power MOSFETs.This IC, which is capable of providing current up to 5A,features fast transient response by employing constanton-time control system. It offers high oscillatingfrequency at low inductance. With its original constanton-time control method which operates low consumptionat light load, this product is ideal for equipment anddevices that demand minimal standby powerconsumption.

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
  • LCD TVs,  Entertainment Devices
  • Printers, OA Equipment
  • Laptop PCs/Tablet PCs/Servers, Storage Devices (HDDs/SSDs)
