Description

BD9B304QWZ 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

  • Single Synchronous Buck DC/DC Converter
  • Constant On-time Control Suitable to Deep-SLLM
  • Over Current Protection
  • Short Circuit Protection
  • Thermal Shutdown Protection
  • Under Voltage Lockout Protection
  • UMMP008AZ020 Package (Backside Heat Dissipation)

Typical applications

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