Beschreibung
BD9B333GWZ is a synchronous buck DC/DC converterwith built-in low on-resistance power MOSFETs. This IC,which is capable of providing current up to 3A, featuresfast transient response by employing constant on-timecontrol system. It offers high oscillating frequency at lowinductance. With its original constant on-time controlmethod which operates low consumption at light load,this product is ideal for equipment and devices thatdemand minimal standby power consumption.BD9B333GWZ achieves the high power density and offera small footprint on the PCB by employing small CSPpackage.
Eigenschaften
Single Synchronous Buck DC/DC Converter Constant On-time Control Suitable to Deep-SLLM Over Current Protection Short Circuit Protection Over Voltage Protection Thermal Shutdown Protection Under Voltage Lockout Protection Adjustable Soft Start Power Good Output UCSP35L1 Package (Resin Coating)
Typische Anwendungen
- Step-down Power Supply for DSPs, FPGAs / Distributed Power Supplies, Secondary Power
- LCD TVs
- Laptop PCs/Tablet PCs/Servers / Storage Devices (HDDs/SSDs) / Printers, OA Equipment
