ROHM BD9A300MUV | Demoboard BD9A300MUV
2.7V to 5.5V Input, Integrated 3A MOSFET 1ch Synchronous Buck DC/DC Converter
Overview
| Topology | Buck Converter |
| Input voltage | 2.7-5.5 V |
| Output 1 | 1.8 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
- Step-down Power Supply for DSPs, FPGAs, Microprocessors, etc.
- Distributed Power Supply, Secondary Power Supply
- LCD TVs / Entertainment Devices
- Laptop PCs/ Tablet PCs/ Servers / Storage Devices (HDDs/SSDs) / Printers, OA Equipment
