BD9104FVM-TR Description

Short technical summary and product information.

The BD9104FVM-TR from ROHM Semiconductor is a high-efficiency, step-down switching regulator designed for applications requiring a stable 3.3V output. This integrated FET synchronous buck converter can deliver up to 0.8A of output current from an input voltage range of 4.5V to 5.5V.

 

Key electrical specifications include a typical switching frequency of 1.0MHz, enabling the use of smaller external components. The device features integrated Nch and Pch FETs for synchronous rectification, contributing to high efficiency across various load conditions. It also incorporates essential protection features such as thermal protection, UVLO (Under-Voltage Lockout), and short-circuit protection with a time delay.

 

The BD9104FVM-TR is housed in an 8-MSOP package, suitable for surface mounting. Its operating temperature range is -25°C to +85°C. This regulator is well-suited for power supply applications in portable electronic devices, HDDs, and for powering LSIs like CPUs and ASICs.

 

The device offers fast transient response due to its current mode PWM control system and high efficiency for all load ranges thanks to synchronous rectification and SLLM (Simple Light Load Mode) technology. It also includes a soft-start function and a shutdown function.
