Description
BD9A100MUV is a synchronous buck switchingregulator with built-in low on-resistance power MOSFETs.It is capable of providing current up to 1A.The SLLMTMcontrol provides excellent efficiency characteristics inlight-load conditions which make the product ideal forequipment and devices that demand minimal standbypower consumption. The oscillating frequency is high at1MHz using a small value of inductance. It is a currentmode control DC/DC converter and features high-speedtransient response. Phase compensation can also be seteasily.
Features
Synchronous Single DC/DC Converter. SLLMTM (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 HeatDissipation)
Typical applications
- Step-Down Power Supply for DSPs, FPGAs, Microprocessors, etc./ Distributed Power Supply, Secondary Power Supply
- Storage Devices (HDDs/SSDs)
- LCD TVs/ Printers, OA Equipment/ Entertainment Devices
