The BD8643FV-E2 from ROHM Semiconductor is a flexible synchronous step-down switching regulator designed for efficient power conversion. It integrates two low-resistance N-channel MOSFETs, enabling it to achieve a 3A continuous output current over a wide input supply range of 4.5V to 18V.
This device features current mode operation for fast transient response and easy phase compensation. Key integrated functions include over-current protection, thermal shutdown, under-voltage protection, and a soft-start circuit. The oscillation frequency is programmable from 100kHz to 600kHz.
The BD8643FV-E2 is suitable for applications such as FPD, DVD, HDD recorders, STBs, and amusement equipment. It is supplied in a 20-SSOP-B surface-mount package.
Key electrical characteristics include a reference voltage of 0.8V ±1%, and an operating temperature range of -20°C to 85°C. The synchronous rectifier design enhances efficiency.
