The BD9139MUV-E2 from ROHM Semiconductor is a high-efficiency, 1-channel synchronous buck converter with integrated FETs. Designed for step-down voltage conversion, it accepts an input voltage from 2.7V to 5.5V and can produce an output voltage as low as 0.8V, up to a maximum of 3.3V. This device is capable of delivering up to 3A of output current.
Key features include a fast transient response due to its current mode PWM control system and high efficiency across all load ranges, achieved through synchronous switches and SLLMTM (Simple Light Load Mode) technology. It also incorporates a soft-start function, thermal shutdown, UVLO (Under-Voltage Lockout), and a time-delayed short-circuit protection function. The switching frequency is typically 1MHz.
The BD9139MUV-E2 is housed in a 16-VQFN (3x3mm) package with an exposed pad for improved thermal performance. Its operating temperature range is -40°C to +105°C. This converter is suitable for power supply applications for LSIs, including DSPs, microcomputers, and ASICs.
