ROHM Semiconductor USA, LLC Voltage Regulators - DC DC Switching Regulators BD95821MUV-E2

The BD95821MUV-E2 is a synchronous buck DC/DC converter designed to operate within an input voltage range of 7.5V to 15V, providing an adjustable output voltage from 0.8V to 5.5V with a maximum output current of 2A. This integrated circuit features built-in N-MOSFET power transistors, which contribute to its compact design and high efficiency. It employs H¬=Reg,Ñ¢ technology for constant ON TIME control, ensuring rapid transient response to load changes without the need for external compensation. Key features include over current protection, thermal shutdown, under-voltage lockout, short circuit protection, and over voltage protection, all of which enhance the reliability of the device. The BD95821MUV-E2 also incorporates a fixed soft start function and a power good output, making it suitable for various applications, including digital AV equipment such as LCD TVs, set-top boxes, and DVD/Blu-ray players. The device is packaged in a 16-pin VQFN format, measuring 3.0mm x 3.0mm x 1.0mm, which facilitates surface mounting in space-constrained designs.
