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)
