Description
BD9B304QWZ 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
- Single Synchronous Buck DC/DC Converter
- Constant On-time Control Suitable to Deep-SLLM
- Over Current Protection
- Short Circuit Protection
- Thermal Shutdown Protection
- Under Voltage Lockout Protection
- UMMP008AZ020 Package (Backside Heat Dissipation)
Typical applications
- Storage Devices (HDDs/SSDs)
- LCD TVs/ Printers/ OA Equipment
- Step-down Power Supply for DSPs, FPGAs, Microprocessors, etc./ Distributed Power Supplies, Secondary Power Supplies
- Laptop PCs/Tablet PCs/Servers
