Description
BD9D321EFJ is a synchronous buck switching regulatorwith built-in low on-resistance power MOSFETs. It iscapable of providing current of up to 3 A. The SLLMTMcontrol provides excellent efficiency characteristics inlight-load conditions which make the product appropriatefor equipment and devices that demand minimal standbypower consumption. External phase compensation circuitis not necessary for it is a constant on-time control DC/DCconverter with high speed response.
Features
Synchronous Single DC/DC Converter Constant On-time Control SLLMTM (Simple Light Load Mode) Control Over Current Protection Short Circuit Protection Thermal Shutdown Protection Under Voltage Lockout Protection Adjustable Soft Start HTSOP-J8 Package (Backside Heat Dissipation)
Typical applications
- Set-top Box/ LCD TVs/ DVD / Blu-ray Player / Recorder/ Entertainment Devices
- Step-down Power Supply for DSPs, FPGAs, Microprocessors, etc.
