The BD9109FVM-TR from ROHM Semiconductor is a step-down switching regulator designed for high efficiency across all load ranges. It utilizes synchronous switches (Nch and Pch FET) and a current mode control system for fast transient response.
Key electrical specifications include an input voltage range of 4.5V to 5.5V and a fixed output voltage of 3.30V with a maximum output current of 800mA. The device operates at a typical switching frequency of 1MHz. It features integrated FETs with a typical ON-resistance of 350mΩ for the Pch and 250mΩ for the Nch. The standby current is a low 0μA typical.
This regulator includes built-in Soft-Start, Thermal Shutdown, ULVO (Undervoltage Lockout), and Short-Circuit Protection with time delay functions. It is suitable for applications requiring stable power supply for LSIs such as DSPs, microcomputers, and ASICs.
The BD9109FVM-TR is available in an 8-MSOP package, measuring 2.90mm x 4.00mm with a maximum height of 0.90mm. The mounting type is surface mount.
