ROHM Semiconductor USA, LLC Dc-Dc Switching Buck Step Down Regulator, Adjustable, 2.7V-5.5Vin, 800Mv-4.4Vout, 3Aout, Vqfn-16 Rohs Compliant Rohm BD9B300MUV-E2

The BD9B300MUV is a synchronous buck DC/DC converter designed for step-down voltage regulation with an input voltage range of 2.7V to 5.5V and an adjustable output voltage from 0.8V to 4.4V. It can deliver a maximum output current of 3A and features a high switching frequency of 2MHz or 1MHz, depending on configuration. The device incorporates built-in low on-resistance power MOSFETs, which contribute to its efficiency and performance. Key protective features include overcurrent protection, short circuit protection, thermal shutdown, and under voltage lockout. The regulator also supports adjustable soft start and has a power good output for monitoring the output voltage status. The package is a VQFN016V3030, which measures 3.00 mm x 3.00 mm x 1.00 mm, allowing for compact integration in various applications. This product is suitable for powering digital signal processors (DSPs), field-programmable gate arrays (FPGAs), microprocessors, and is applicable in devices such as laptops, tablets, servers, LCD TVs, and storage devices. Its low standby current makes it ideal for applications requiring minimal power consumption during idle states.
