ROHM BD9B300MUV | Demoboard BD9B300MUV
2.7V to 5.5V Input, 3.0A Integrated MOSFET Buck DC/DC Converter
Overview
| Topology | Buck Converter |
| Input voltage | 4.13-5.5 V |
| Switching frequency | 1000-2000 kHz |
| Output 1 | 3.3 V / 3 A |
| IC revision | 004 |
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
