Description
BD9B200MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. This IC, which is capable of providing current up to 2A, 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
- Storage Devices (HDDs/SSDs)
- LCD TVs/ Printers/ OA Equipment/ Entertainment Devices
- Laptop PCs/Tablet PCs/Servers
- Step-down Power Supply for DSPs, FPGAs,Microprocessors, etc. Distributed Power Supply, Secondary Power Supply
