ROHM BD9A300MUV | Demoboard BD9A300MUV

2.7V to 5.5V Input, Integrated 3A MOSFET 1ch Synchronous Buck DC/DC Converter

Overview

TopologyBuck Converter
Input voltage4.71-5.5 V
Output 13.3 V / 3 A

Description

BD9A300MUV is a synchronous buck switching regulator with built-in low On-resistance power MOSFETs. It is capable of providing current up to 3A. The SLLM™ 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
  • SLLM (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 Heat Dissipation)

Typical applications

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