IC revision001

Description

BD9B100MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. This IC, which is capable of providing current up to 1A, 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 Supplies, Secondary Power
  • Laptop PCs / Tablet PCs/Servers LCD TVs, Printers, OA Equipment, Entertainment Devices
  • Storage Devices (HDDs/SSDs)
